- If vim is executed in WSL in mintty, some garbage string caused
by "OSC Ps;? BEL/ST" will be shown in some situations. This patch
fixes the issue by removing "OSC Ps;? BEL/ST" from pseudo console
output.
Since we are now only configuring once, in winsup, with
AC_CONFIG_AUX_DIR(..), the auxiliary files are taken from the top-level.
(Previously we had a random assorment of AC_CONFIG_AUX_DIR(..) and
AC_CONFIG_AUX_DIR(../..) in winsup subdirectories, so auxiliary files
would be taken from winsup or the top-level.)
There's doesn't seem to be much use in independently distributing these
subdirectories, so allowing them to be independently configured seems
pointless and overcomplicated.
The order in which the subdirectories are built is still a little odd,
as cygwin is linked with libcygserver, and cygserver is then linked with
cygwin. So, we build the cygwin directory first, which invokes a build
of libcygserver in the cygserver directory, and then build in the
cygserver directory to build the cygserver executable.
Drop AC_CONFIGURE_ARGS, since we don't need to recursively call
configure with the same arguments anymore.
Slightly refine when we build utils: Previously we didn't build any
utils if MinGW compiler use was avoided, now we just avoid building
those utils which require that compiler.
Greatly simplify how winsup_srcdir and target_builddir are set, since
we're only configuring from one directory. (These are still kept
absolute, since we don't adjust them where used for being used in a
subdirectory).
Remove configure.cygwin and put it's (greatly reduced) contents inline
in the one place it's used now.
Remove generated configure and aclocal.m4 in subdirectories.
This has a test of the path translation code used in various utilities
(mount, cygpath, strace).
MOUNT_BINARY is replaced with the absence of MOUNT_TEXT since 26e0b37e.
The issys member of mnt_t struct was removed in b677a99b.

'-fno-exceptions -fno-rtti' are already present in the compile command
COMPILE.cc set by Makefile.common, so we don't need to add them to
CXXFLAGS as well.
Invoke grep in text mode when looking for version strings inside the
cygwin DLL, so it outputs something more informative than:
Binary file ../cygwin/cygwin0.dll matches
The overflow check in mEMALIGn erroneously checks for INT_MAX,
albeit the input parameter is size_t. Fix this to check for
__SIZE_MAX__ instead. Also, it misses to check the req against
adding the alignment before calling mALLOc.
While at it, add out-of-bounds checks to pvALLOc, nano_memalign,
nano_valloc, and Cygwin's (unused) dlpvalloc.

Replace the 'WCHAR pipe_name_buf[48]' class member by 'PWCHAR
pipe_name_buf', and allocate space for the latter as needed.
Change the default constructor to accommodate this change, and add a
destructor that frees the allocated space.
Also change get_pipe_name and clone to accommodate this change.
By default, libltp tests will create temporary files in a subdirectory
of /tmp, which will (nowadays) be located relative to the test DLL (by
assuming that it is in /bin). This will evaluate to the directory
$target_builddir/winsup/tmp, which doesn't exist.
The location used for these temporary files can be explicitly controlled
by setting the TDIRECTORY env var. Arrange to set that env var to the
/cygdrive path of a tmp subdirectory of the build directory.
Unfortunately, libltp doesn't clean the temporary directory if
TDIRECTORY is set, and some tests assume they are started in a clean
directory, so we need to do that in tcl.
Set the PATH so that tests can pick up cygwin0.dll. Looks like this was
dropped by accident in 2e488e95 ("Don't rely on in-build tools"), so
restore it as it was prior to 9d89f634.
Drop MINGW_FE, which I can't find any trace of, and instead detect and
use MinGW compilers.
This requires adding AC_CANONICAL_TARGET, to set $target_cpu.
This is now required as cygwin_build is defined in terms of
target_builddir.
(Note that in other subdirectories, the autoconf variable
target_builddir is AC_SUBST-ed as a side-effect of using a macro from
winsup/acinclude.m4, which is perhaps less than ideal)
The autoconf variable all_host is used to make building of the stub
library used by the testsuite conditional on not cross-compiling.
Make it unconditional, so we will notice if it's broken when
cross-compiling.
b55e3f19 was a bit too aggressive in dropping, rather than just
un-exporting these Makefile variables. We need to set these to the
configured host compiler if we are cross-compiling, otherwise they
default to the build compiler.
Also export CC to the mkvers.sh script (which requires it since
4eca5e6a). It's unclear why we can't just cause windres to use the
build 'cpp' as the pre-processor there.
The return value is now -NaN.
This fixes a bug in the mingw-w64 code that was imported into Cygwin.
The fix is consistent with Posix and Linux. It is also consistent
with the current mingw-w64 code, with one exception: The mingw-w64
code sets errno to EDOM if the input is -NaN, but this appears to
differ from Posix and Linux.

- Calling ResizePseudoConsole() generates some escape sequences.
Due to this behaviour, if the output of non-cygwin app is piped
to less, screen is sometimes distorted when the screen is resized.
With this patch, ResizePseudoConsole() is not called if stdout is
redirected.
