GNU no longer encourages the use of documentation mirrors, to avoid
referring to obsolete documentation. Also www.fsf.org/manual/ is
just a redirect to www.gnu.org/manual/
Links to using-utils.html #fragments are no longer correct as each utility
is now a separate page, since 646745cb.
indiana.edu seems to have moved XLiveCD information, without a redirect.
Linking to clean_setup.pl on cygwin.com doesn't work, as direct downloads
aren't allowed, so instead state where it can be found on a mirror.

Include ntsecapi.h where required and just redefine RtlGenRandom
correctly in the ntsecapi.h wrapper.

In preparation of exporting getentropy/getrandom to userspace, rearrange
code a bit:
- Define RtlGenRandom in ntdll.h.
- Drop calls to getentropy in favor of RtlGenRandom (fhandler_socket,
fhandler_dev_random).
- Add try/except blocks in fhandler_dev_random to return EFAULT rather
than crashing if buffer pointer is invalid.

NtOpenFile/NtCreateFile on non-existent paths on network drives has a
bug. Assuming a path Z:\dir\file. Further assuming that Z:\dir does
not exist.
The first NtOpenFile("Z:\dir\file") correctly returns
STATUS_OBJECT_PATH_NOT_FOUND. Subsequent calls incorrectly
return STATUS_OBJECT_NAME_NOT_FOUND.
This appears to be some kind of caching behaviour. Waiting a while
before repeating the call correctly returns STATUS_OBJECT_PATH_NOT_FOUND
again.
This patch works around the observed misbehaviour.

So far, when converting from POSIX to Windows notation, cygwin_conv_path
fails to check for .exe suffix, so /path/foo did not return /path/foo.exe
even if this file exists.

The original code only skipped the "./", but missed to test if more
trailing slashes are present. This in turn leads to invalid conversion.

Provide <memory.h> for all standard Newlib targets and remove
Cygwin-specific header. Most POSIX like systems provide this historic

This makes it possible provide operating system specific types for
<pthread.h>. It is in line with the FreeBSD header file structure and
allows a future cleanup of <pthread.h> to not expose unrelated things
via <sys/types.h> and <unistd.h>. Glibc uses the similar
<bits/pthreadtypes.h> for this purpose.

Update the getconf utility to support the new flag as well as
_PC_POSIX_PERMISSIONS and _PC_POSIX_SECURITY. These were previously
unsupported, probably as an oversight.

Additionally to eccefd97, we need to ensure the exception handler is
installed for the _ljfault used to implement _try/_except to get called.
Also use the correct macro for x86 conditional compilation.

Long-standing problem in one of the corner cases of rename(2):
If we rename a directory a check is performed to see if newpath is
identical to oldpath or a subdir of oldpath. This check is
(accidentally? no hints anywhere in ChangeLogs or code) performed
case-insensitive for as long as we use Unicode paths and NT functions.
This leads to the problems described in
https://cygwin.com/ml/cygwin/2016-09/msg00264.html
Change this to be conditional case-sensitive as all other checks but
let's take this with a grain of salt. There may be corner-cases in
this corner-case which require to chek parts of the path always
case-insensitive. Off the top of my head I can't construct such a
case but that's no proof they don't exist :}

Commit d16a5630 dropped usage of cygheap's locale functions
in favor of local on-the-fly usage of UTF-8 instead of ASCII.
This allowed to use the current local rather than a fixed
system-wide locale set at startup time. d16a5630 just missed
to add the ASCII->UTF-8 conversion in the console as well.

Yep.

No problem - attached.
This renders the original patch 4/4 valid again.

Same here.

Subject: [PATCH 3/4] dlopen: on x/lib search x/bin if exe is in x/bin
citing https://cygwin.com/ml/cygwin-developers/2016-08/msg00020.html
> Consider the file /usr/bin/cygz.dll:
> - dlopen (libz.so) success
> - dlopen (/usr/bin/libz.so) success
> - dlopen (/usr/lib/libz.so) fails
* dlfcn.c (dlopen): For dlopen("x/lib/N"), when the application
executable is in "x/bin/", search for "x/bin/N" before "x/lib/N".
Rather than searching all search dirs per one basename,
search for all basenames within per one search dir.
pathfinder.h (check_path_access): Interchange dir- and basename-loops.
