I wanted to import the pathmax module, and that pulls in the unistd module as dependency. The unistd module is actually bigger than the pathmax module. If we're going to end up with it, might as well import it explicitly, and make use of it throughout. The "unistd" module makes a GNU-like <unistd.h> always available. This means we no longer need to do: +#ifdef HAVE_UNISTD_H #include <unistd.h> +#endif and we can remove a few constants from defs.h. This is just the importing step. gdb/ 2013-07-01 Pedro Alves <palves@redhat.com> Import the "unistd" gnulib module. * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add "unistd". * gnulib/Makefile.in (aclocal_m4_deps): Add import/m4/off_t.m4, import/m4/ssize_t.m4, import/m4/sys_types_h.m4 and import/m4/unistd_h.m4. * gnulib/aclocal.m4: Renenerate. * gnulib/config.in: Renenerate. * gnulib/configure: Renenerate. * gnulib/import/Makefile.am: Renenerate. * gnulib/import/Makefile.in: Renenerate. * gnulib/import/m4/gnulib-cache.m4: Renenerate. * gnulib/import/m4/gnulib-comp.m4: Renenerate. * gnulib/import/m4/off_t.m4: New file. * gnulib/import/m4/ssize_t.m4: New file. * gnulib/import/m4/sys_types_h.m4: New file. * gnulib/import/m4/unistd_h.m4: New file. * gnulib/import/sys_types.in.h: New file. * gnulib/import/unistd.c: New file. * gnulib/import/unistd.in.h: New file.
