Subject: On NextStep, <utime.h> doesn't define struct utime, unless we
X-Git-Url: http://git.hcoop.net/bpt/guile.git/commitdiff_plain/2420229da7870ae950c0bdda8dc76f99cdac179b?hp=5bc433f5fd1dd7fd06478548d5dcda7e9345dd93

On NextStep, <utime.h> doesn't define struct utime, unless we
#define _POSIX_SOURCE before #including it.
* aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
* acconfig.h: New comment text for above CPP symbol.
* configure.in: Call it.
* posix.c: #define _POSIX_SOURCE if it seems necessary.
