MOUNT_BINARY is replaced with the absence of MOUNT_TEXT since 26e0b37e.

'-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.
to rb parent pointers. Define RB_SWAP_CHILD to replace the child of a parent
with its twin, and use it in 4 places. Use RB_SET in rb_link_node to remove the
only linuxkpi reference to color, and then drop color- and parent-related
definitions that are defined and used only in rbtree.h.
This is intended to be entirely cosmetic, with no impact on program
behavior, and leave RB_PARENT and RB_SET_PARENT as the only ways to
read and write rb parent pointers.

the sibling of the root of the too-short tree is black and at least one of the
children of that sibling is red, either one or two rotations finish the
rebalancing. In the case when both of the children are red, the current
implementation uses two rotations where only one is necessary. This change
removes that extra rotation, and in that case also removes a needless
black-to-red-to-black recoloring.
