At the end of this messiage is a patch I imported from a pending glibc patch.
By the way, can anybody explain the following comment in m4/include_next.m4? dnl gcc does not warn about some things, and on some systems (Solaris and Interix) dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead dnl of plain '__STDC__'. I don't understand this, as no gnulib code seems to use 'defined __STDC__' in that way. obstack: remove __STDC__ conditionals * lib/obstack.h: Remove __STDC__ conditionals, as suggested by Joseph S. Myers in <http://cygwin.com/ml/libc-alpha/2012-01/msg00104.html>. This leaves lib/localcharset.c, m4/iconv.m4, and a confusing comment in m4/include_next.m4 as the only gnulib-maintained places that still refer to __STDC__. diff --git a/lib/obstack.h b/lib/obstack.h index 0a1e473..b7d2404 100644 --- a/lib/obstack.h +++ b/lib/obstack.h @@ -253,7 +253,7 @@ extern int obstack_exit_failure; #define obstack_memory_used(h) _obstack_memory_used (h) -#if defined __GNUC__ && defined __STDC__ && __STDC__ +#if defined __GNUC__ /* NextStep 2.0 cc is really gcc 1.93 but it defines __GNUC__ = 2 and does not implement __extension__.
