2012-08-01 extern-inline: new module
2012-08-01 stat-time, timespec, u64, utimens: use extern-inline
* lib/stat-time.c, lib/utimespec.c, lib/u64.c, m4/extern-inline.m4:
New files.  The new .c files are for instantiating extern inline
functions.

Merge from gnulib (Bug#12116), incorporating:
2012-08-01 extern-inline: new module
2012-08-01 stat-time, timespec, u64, utimens: use extern-inline
* lib/stat-time.c, lib/utimespec.c, lib/u64.c, m4/extern-inline.m4:
New files. The new .c files are for instantiating extern inline
functions.
Port to Solaris 8.
Without this change, 'configure' fails because the recently-added
wait3 prototype in config.h messes up later 'configure' tests.
