* cygwin: make POSIX/XSI version macros dependent on feature test macrosYaakov Selkowitz2016-04-041-10/+37
| | | | | | | | | | | | | Each version of SUS specifies a different value for _POSIX_VERSION, _POSIX2_VERSION, and _XOPEN_VERSION. glibc also changes the value of the other _POSIX2_ variables but not the _POSIX_* variables. _POSIX_TIMERS should be set to a version number, not just 1. The _POSIX_V7_* macros were missing, which was not noticed because the V6 values were aliased in sysconf (<unistd.h>). Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: C++ TR1Yaakov Selkowitz2016-03-231-5/+5
| | | | | | | | | | | | While C++11 was the first version of the standard to use C99 functionality, TR1 (for C++03) also does, and G++ does not distinguish between C++98 and C++03, or when TR1 is in use. Therefore, while not strictly correct for "pure" C++98, enabling C99 for all C++ usage is the simplest solution (and much better than always using -D_GNU_SOURCE as on Linux).

* Feature test macros overhaul: sys/features.hYaakov Selkowitz2016-03-171-19/+275
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the complete rework of the feature tests macros for better compatibility with GNU libc, primarily based on the Linux man pages documentation: http://man7.org/linux/man-pages/man7/feature_test_macros.7.html The previous implementation was flawed in its approach that macros were often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or !defined _POSIX_SOURCE), whereas the approach of glibc is that these macros make symbols available when defined (e.g. defined _BSD_SOURCE, or as used internally, #if __BSD_VISIBLE). As much open-source software is written with glibc in mind, this necessitated patching numerous packages just to compile. In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*) was given too much importance. This implementation limits the influence of __STRICT_ANSI__ to controlling the default when no other feature test macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as documented. These are the only places where __STRICT_ANSI__ should be tested. The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE, _DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE, _SVID_SOURCE, _XOPEN_SOURCE_EXTENDED. The existing __*_VISIBLE internal macros have been kept mostly compatible with the original BSD implementation, with some changes to the criteria which controls them. Several more macros in this style have been added where needed for concision or accuracy. Enabling C++11 or newer in the compiler also enables C99 and C11 functions. Doing so should help move away from the need to define _GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51749 Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Define the newlib version macros in one place: _newlib_version.h.Pieter du Preez2016-02-171-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 stamp-* files Signed-off-by: Pieter du Preez <pdupreez@gmail.com>
