-# DESCRIPTION
#
-# This macro determines whether the _XOPEN_SOURCE with
-# _XOPEN_SOURCE-VALUE really enable some header features. FEATURES_TEST
-# must contains required includes and main function.
-# One of ACTION-IF-ENABLED-BY-XOPEN_SOURCE and ACTION-IF-NOT
-# is always executed depending on test results.
-# One of ACTION-IF-FEATURES-AVALABLE and is ACTION-IF-FEATURES-NOT-AVALABLE
-# is executed if features can be enabled by _XOPEN_SOURCE, by currently
-# defined (by compiler flags or by predefined macros) extensions or
-# all checked combinations are failed to enable features.
-# ACTION-IF-ONLY-WITH-EXTENSIONS is executed if features can be
-# enabled with not undefined extension.
-# ACTION-IF-WITHOUT-ALL is executed if features work with all
-# disabled extensions (including _XOPEN_SOURCE).

- [GNUnet-SVN] [libmicrohttpd] branch master updated: mhd_sys_extentions.m4: updated, fixed and improved. Now better detect supported features, works with latest Android NDK, skips definition of _XOPEN_SOURCE on platforms where it conflicts with system-specific features, overall improvements and minor fixing.,
