Yoshinao Muramatsu 527dd1b407 Cygwin: fix unlink in container
Deleting files returns STATUS_INVALID_PARAMETE on a bind mounted file system
in hyper-v container with FILE_DISPOSITION_POSIX_SEMANTICS.
Therefore fall back to default method.

This code is suggested by Johannes Schindelin on github
and I change it more simple.

Corinna Vinschen fe2545e9fa Cygwin: don't use unlink/rename POSIX semantics on certain NTFS
If a host NTFS is mapped into a Hyper-V isolated container, the
OPEN_BY_FILE_ID filesystem flag is missing, just as if that NTFS
is a remote drive.  However, NtQueryVolumeInformationFile claims
the drive is a local drive.

We can use this fact to learn that the process is running under
Hyper-V, and that the Hyper-V isolated process can't use rename/unlink
with POSIX semantics.  Strange enough, the POSIX_UNLINK_RENAME filesystem
flag is still set...

These flags are used to check a remote filesystem.  Not all
flags supported by a local NTFS are available when checking
a remote NTFS.  Fix the flag set accordingly, otherwise
the remote NTFS will ba handled as CIFS.

Corinna Vinschen 5924191333 Cygwin: regex: fix faulty check for valid range expression
Except for the "C" or "POSIX" locale, checking for start <= finish
is always wrong.  Range start must be <= range finish in terms of the
locale's collating order.  So make sure to call always wcscoll(), even
in the "C"/"POSIX" locale, which makes wcscoll equivalent to wcscmp
anyway.

Corinna Vinschen e914374383 Cygwin: regex: fix freeing g->charjump in low memory condition
computejumps() moves g->charjump to a position relativ to the value of
CHAR_MIN.  As such, g->charjump doesn't necessarily point to the address
actually allocated.  While regfree() takes that into account, the low
memory handling in regcomp_internal() doesn't.  Fix that by free'ing
the actually allocated address, as in regfree().

Mark Geisert dfd14093e3 Cygwin: Fix type mismatch on sys/cpuset.h
Addresses https://cygwin.com/pipermail/cygwin/2023-March/253220.html

Take the opportunity to follow FreeBSD's and Linux's lead in recasting
macro inline code as calls to static inline functions.  This allows the
macros to be type-safe.  In addition, added a lower bound check to the
functions that use a cpu number to avoid a potential buffer underrun on
a bad argument.  h/t to Corinna for the advice on recasting.

Corinna Vinschen 6bc687e35d Cygwin: glob: fix conversion from UTF-32 to multibyte
The conversion function g_Ctoc missed to drop the flag
values from the wint_t value.  That wasn't noticable with
the original version because it used a 64 bit Char type
and the flags were in the upper 32 bit region.  So the
flag values were silently dropped when wcrtomb was called.
After converting Char to wint_t, we have to do drop the
flags explicitely.

Corinna Vinschen c36064bbd0 Cygwin: fnmatch: support collating symbols in [. .] brackets
This requires quite a few changes in how fnmatch operates.
It always operates on wint_t strings now, just like regex and glob,
and it always keeps a pointer on the character inside the string,
rather than operating on a single character.

As a result, just drop the ifdef's for Cygwin.  The code is
non-portable now anyway...
