This is a followup to edfca3b7e5, which
added the 'posix_spawnp' module but not 'posix_spawn'.
* m4/gnulib-cache.m4: Add 'posix_spawn' module.
* gnulib-local/m4/clock_time.m4.diff: Adjust.
* configure.ac: Move 'gl_EARLY' use right after 'AC_PROG_CC'.
This reverts commit 2d4da30fde.
This Gnulib update was causing failures related to timezones in
stime.c. I tried to fix it by adopting the time_rz module from gnulib
but that then caused other failures. We can try again later.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
From Gnulib v0.0-4889-ge375fe3.
* m4/gnulib-cache.m4: Add `log1p' and `round', requested by
Mark H Weaver <mhw@netris.org>.
Use `malloc-gnu' instead of `malloc', the latter being obsolete.
