* Fix build on newer glibc.Eric Blake2010-06-043-0/+10
| | | | | | | | | | | | POSIX allows, but does not require, that <fcntl.h> implicitly includes <sys/stat.h>. Until recent glibc, most systems did this implicit inclusion, and m4 was mistakenly relying on it. * src/m4.h (includes): Add <sys/stat.h>. * THANKS: Update. Reported by Todd Rinaldo. Signed-off-by: Eric Blake <eblake@redhat.com>
* Support bootstrap --gnulib-srcdir=DIR.Giuseppe Scrivano2010-06-042-1/+15
| | | | | | | | | | | | | | I saw `bootstrap' doesn't accept --gnulib-srcdir as it is already done by other projects using gnulib. It doesn't add a new feature as it can be already done specifying GNULIB_SRCDIR, it just make the script more similar to scripts used by other projects doing a bootstrap from gnulib. * bootstrap: Add --gnulib-srcdir option, which overrides GNULIB_SRCDIR, for consistency with gnulib bootstrap.
