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.

* configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
in the list.
* posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
testing for __EMX__.
