Currently, the newlib version information needs to be updated in two places:
- newlib/acinclude.m4
- newlib/libc/include/sys/features.h
The goal of this patch is to:
- supply a single location for defining the newlib version
information: newlib/acinclude.m4
- define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__
This is in line with what gcc does for its version macros. See:
https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html
This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__
and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h,
to the newly generated newlib/_newlib_version.h file. Additionally,
the __NEWLIB_PATCHLEVEL__ macro was created, for completeness.
In order to stay backwards compatible, newlib/_newlib_version.h gets
included by newlib/newlib.h and newlib/libc/include/sys/features.h.
Note: This patch does _not_ include the modifications to the following
files, as these should all be generated any way.
*Makefile.in,
*aclocal.m4,
*configure

This follows up from my msg re GMP-ECM failing its 'make check' on the
main list https://cygwin.com/ml/cygwin/2016-02/msg00147.html .
There's an error that ought to be reported during dynamic linking if the
linked-to address is too far from the relocation site. However the error
is not reported if __OPTIMIZE__ was #defined when building the Cygwin DLL.
I can't see why optimization settings should affect this.

In case of non-reentrant system calls _sbrk_r became a macro with TWO
args (defined in reent.h):
#define _sbrk_r(__reent, __incr) sbrk(__incr)
But in our case only one argument is present. (RCALL 0) is considered
as a single argument despite RCALL itself is a macro:)
So intermediate one-arg macro will be enough to expand args before
final _sbrk_r expansion:
#define _SBRK_R(X) _sbrk_r(X)

POSIX.1e requires that chmod changes the MASK rather than the
GROUP_OBJ value if the ACL is non-trivial.
On Windows, especially on home machines, a standard ACL often
consists of entries for the user, maybe the group, and additional
entries for SYSTEM and the Administrators group. A user calling
chmod on a file with bog standard Windows perms usually expects
that chmod changes the GROUP_OBJ perms, but given the rules from
POSIX.1e we can't do that.
However, since we already treat Admins and SYSTEM special in a
ACL (they are not used in MASK computations) we go a step in the
Windows direction to follow user expectations. If an ACL only
consists of the three POSIX permissions, plus entries for Admins
and SYSTEM *only*, then we change the permissions of the GROUP_OBJ
entry *and* the MASK entry.

On Cygwin 32 running under WOW64:
When case-correcting the path fetched with -S, the underlying
Windows function fetching the normalized path returns the real
path C:\Windows\SysWOW64 instead of the path redirection
enabled C:\Windows\System32 path. This breaks using the result
of `cygpath -S' to fetch the POSIX path of the network related
files under SYSTEMROOT\drivers\etc. This path is in fact under
the *real* C:\Windows\System32 and only mapped into the 32 bit
C:\Windows\System32 (aka C:\Windows\SysWOW64) via path redirection.
Sounds messy?
This patch checks if we're running under WOW64. If so, it
changes the path returned by GetSystemDirectoryW from "system32"
to "Sysnative". This in turn is changed to "System32" by
NtQueryInformationFile, so we're back to what we need.
