Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.
Other than that, cygwin_props were meant to be used for some other global
settings which never took place. There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.
This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

Hi.
I have noticed that Cygwin's spinlock goes into heavy sleeping code
for each spin. It seems it would be a good idea to actually try to

CPU make such busy loops be less busy. Here is a patch to do this.

This patch set modifies Cygwin's profiling support to sample PC values
of all an app's threads, not just the main thread. There is no change
to how profiling is requested: just compile and link the app with "-pg"
as usual. The profiling info is dumped into file gmon.out as always.
A new facility enabled via the environment variable GMON_OUT_PREFIX.
This facility is intended to match an undocumented Linux glibc feature.
Exporting the variable with a non-empty value such as "foo" causes the
profiling info to go to a file named foo.$pid instead of the default.
With that, both resulting processes of a fork() can have their profiling
data captured in separate files. gprof already knows how to accumulate
data from multiple files if they all pertain to the same app.
There is no change to the normal Cygwin execution paths if profiling is
not enabled. And when it is enabled, only the one profiling thread per
profiled app is doing more work than it used to.

Originally, using RtlGetVersion instead of GetVersionEx was supposed to

executable has been built with an old manifest (or none at all), starting
with Windows 8.1. Either this never really worked as desired and our
testing was flawed, or this has been changed again with Windows 10, so
that RtlGetVersion does the kernel faking twist as well. Since we're
only reading the value in the first process in a process tree. the entire
process tree is running with a wrong OS version information in that case.
Fortunately, the (undocumented) RtlGetNtVersionNumbers function is not
affected by this nonsense, so we simply override the OS version info
fields with the correct values now.

The problem this patch fixes showed up after updating to gcc-5.3.0. The
cuplrit is a change in gcc when emitting section attributes. It only
shows up when building without optimization. Effect in Cygwin: ws2_32
functions failed to load.
In the original code the definition of "NO_COPY wsadata" was preceeding
an __asm__ block (the definition of the _wsock_init wrapper), while the
definition of "NO_COPY here" immediately follows the same assembler
block. When gcc-5.3.0 emits assembler code for the wsadata definition,
it emits the .data_cygwin_nocopy section attribute.
Next it emits the assembler output for the __asm_ block, entirely ignoring
its content. The __asm__ block adds a .text section definition.
Eventually gcc emits assembler code for the here definition. However,
apparently gcc still "knows" that it just emitted the .data_cygwin_nocopy
section attribute and so doesn't redefine it. Remember the __asm__? It
changed the section to .text.
So with gcc-4.9.3 we got:
.section .data_cygwin_nocopy,"w"
wsadata:
__asm__ block:
.text
.section .data_cygwin_nocopy,"w"
here:
With gcc 5.3.0 we now get:
.section .data_cygwin_nocopy,"w"
wsadata:
__asm__ block:
.text
here:
So "here" is now in the .text segment which is read-only. Hilarity ensues.

after some discussion on irc and the list i'm resubmitting a simpler
version of the patch.
setting the locale on cygwin to 'C.UTF-8' is not needed, so i'm always
setting it to 'C' which is sufficient for the build process and the
most simple fix.
short explanation: after setting up cygwin on my systems the default
locale is set to "de_DE.UTF-8". this leads to ccwrap not picking up
certain "-isystem" arguments, which in turn leads to "stddef.h: no such
file or directory". this breaks the build process for systems having non
english locale.
ccwrap scans the output of the first compiler invocation (line 21) for
some specific english output on and around line 43.
i changed the patch to check uname -o for cygwin string and set the
locale to either C or C.UTF-8
Fix various 32/64-bit portability issues in ssp, the single-step profiler, and
also build it for 64-bit.
This didn't turn out to actually be very useful for what I wanted to use it for,
so it's only been lightly tested.
It appears that on x86_64, single-step exceptions occur for much more of the
code in system DLLs, unlike x86, so ssp may take much, much longer to profile
some programs. There is existing code to use breakpoints to mitigate this, but
that is currently disabled.

POSIX.1e requires that chmod changes the MASK rather than the
GROUP_OBJ value if the ACL is non-trivial.
On Windows, especially on home machines, a standard ACL often
consists of entries for the user, maybe the group, and additional
entries for SYSTEM and the Administrators group. A user calling
chmod on a file with bog standard Windows perms usually expects
that chmod changes the GROUP_OBJ perms, but given the rules from
POSIX.1e we can't do that.
However, since we already treat Admins and SYSTEM special in a
ACL (they are not used in MASK computations) we go a step in the
Windows direction to follow user expectations. If an ACL only
consists of the three POSIX permissions, plus entries for Admins
and SYSTEM *only*, then we change the permissions of the GROUP_OBJ
entry *and* the MASK entry.

On Cygwin 32 running under WOW64:
When case-correcting the path fetched with -S, the underlying
Windows function fetching the normalized path returns the real
path C:\Windows\SysWOW64 instead of the path redirection
enabled C:\Windows\System32 path. This breaks using the result
of `cygpath -S' to fetch the POSIX path of the network related
files under SYSTEMROOT\drivers\etc. This path is in fact under
the *real* C:\Windows\System32 and only mapped into the 32 bit
C:\Windows\System32 (aka C:\Windows\SysWOW64) via path redirection.
Sounds messy?
This patch checks if we're running under WOW64. If so, it
changes the path returned by GetSystemDirectoryW from "system32"
to "Sysnative". This in turn is changed to "System32" by
NtQueryInformationFile, so we're back to what we need.

Our WCS -> UTF conversion handles the private Unicode page specially

no sense for command-lines, nor environment variables, which we would
rather convert verbatim.
As a stop-gap solution, let's just introduce a version of the
sys_wcstombs() function that specifically excludes that file name
conversion magic.
The proper solution is to change sys_wcstombs() to assume that it is not
a path that wants to be converted, and introduce sys_wcstombs_path()
that does, but that is a bigger task which we leave for another patch.
