POSIX requires that SSIZE_MAX have the same type as ssize_t, but
on 32-bit, we were defining it as a long even though ssize_t
resolves to an int. It also requires that SSIZE_MAX be usable
via preprocessor #if, so we can't cheat and use a cast.
If this were newlib, I'd have had to hack _intsup.h to probe the
qualities of size_t (via gcc's __SIZE_TYPE__), similar to how we
already probe the qualities of int8_t and friends, then cross our
fingers that ssize_t happens to have the same rank (most systems
do, but POSIX permits a system where they differ such as size_t
being long while ssize_t is int). Unfortunately gcc gives us
neither __SSIZE_TYPE__ nor __SSIZE_MAX__. On the other hand, our
limits.h is specific to cygwin, so we can just shortcut to the
correct results rather than being generic to all possible ABI.

fhandler_base::open_fs has two problems:
- When newly creating a file, the file info in the path_conv is
incorrect. It points to info for the parent dir, not to info
for the file itself (which, naturally, wasn't available before).
- Fetching the file's inode number only worked for non-NFS.
Both problems should be fixed now by reloading file info if the file
has just been created, as well as using the new FS-agnostic

Commit a23e6a35d8 introduced a timer
object to the WFMO handling in select_stuff::wait to allow sub-tickcount
timeout values in select.
Problems with this patch: The timer was created and destroyed on every
invocation of select_stuff::wait, thus potentially multiple times per
select. Also, since the timer was prepended to the WFMO hande list,
the timer handle could shadow actual events on other objects, given that
WFMO checks the objects in the order they have been specified in the
HANDLE array. The timer was also created/destroyed and added to the
HANDLE array even if it was not required.
This patch drops the local timer HANDLE and recycles the cw_timer HANDLE
in the cygtls area instead. Thus we typically don't need to create the
timer in select at all, and we never have to destroy it.
The timer HANDLE is now also appended as last object to the HANDLE array,
and it's only added if actually needed.

So far pthread::postcreate() only sets the thread priority at all, only

So far the scheduler priority handling is not POSIX compatible.
The priorities use a range of -14 up to +15, which means it's not clear
if the POSIX-required return value of -1 in case of an error is *really*
an error or just the valid priority value -1. Even more confusing, -14
is the *max* value and 15 is the *min* value. Last but not least this
range doesn't match the POSIX requirement of at least 32 priority values.
This patch cleans up scheduler priority handling and moves the valid
priority range to 1 (min) - 32 (max). It also adds a function
sched_get_thread_priority() which will help to make thread priority

For all pthread init functions, POSIX says

We can't handle the S_ISGID bit if the child didn't inherit a NULL SID
ACE with the S_ISGID bit set. On directories without default ACL

This in turn results in permission problems when calling set_file_sd

for files created from Cygwin while files created from native Windows
tools end up with really ugly permissions.
This patch only makes sure that the S_ISGID bit is reset for a directory

Newlib uses single underscore types for some internal types, e.g.
_off_t. However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.
The header file <machine/types.h> is Newlib-specific. It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t. Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets). This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target). Use the standard <sys/_types.h> include throughout.
Move __loff_t defintion to default (non-Linux) <sys/_types.h>. Define
it via _off64_t to avoid a dependency on the compiler.
Provide the __off_t definition via default (non-Linux) <sys/_types.h>

Cygwin's strxfrm/wcsfrm treated a too short output buffer as an error
condition and always returned the size value provided as third parameter.
This is not as it's documented in POSIX.1-2008. Rather, the only error

Other than that, the functions are supposed to return the length of the

case the content of the output array is unspecified, but it's the job
of the application to check that the return value is greater or equal to
the provided buffer size.

In 7346568 (Make requested console reports work, 2016-03-16), code was
introduced to report the current cursor position. It works by using a
pointer that either points to the next byte in the readahead buffer, or
to a NUL byte if the buffer is depleted, or the pointer is NULL.
These conditions are heeded in the fhandler_console::read() method, but
the condition that the pointer can point at the end of the readahead
buffer was not handled properly in the get_cons_readahead_valid()
method.
This poses a problem e.g. in Git for Windows (which uses a slightly
modified MSYS2 runtime which is in turn a slightly modified Cygwin
runtime) when vim queries the cursor position and immediately goes on to
read console input, erroneously thinking that the readahead buffer is
valid when it is already depleted instead. This condition results in an
apparent freeze that can be helped only by pressing keys repeatedly.
The full Git for Windows bug report is here:
https://github.com/git-for-windows/git/issues/711

Rename without-mingw-progs to with-cross-bootstrap, since it now
disables additional checks that are problematic for cross-compilers.
When cross-compiling a toolchain targeting cygwin, building cygwin1.dll
requires libgcc.
However, building libgcc requires the cygwin headers to be
installed.
Configuring cygwin requries the mingw-crt libraries, which require the
cygwin headers to be installed.
Work around this circular dependency by making the
--with-cross-bootstrap configure option skip cygwin's configure checks
for valid mingw-crt libraries. Cygwin will still properly link against
these libraries if they exist, but this allows configure to succeed even
if the libraries have not been built yet.
Since the mingw-crt libraries only require the cygwin headers to be
installed, this allows us to successfully configure cygwin so that we
can only install the headers without trying to build any
libraries.
