[PATCH 2/2] Import strtok_r gnulib module

Pedro Alves
2015-04-08T17:19:58Z

gdb/linux-tdep.c recently gained a strtok_r use. That broke
--enable-targets=all with some versions of mingw64, which don't have
strtok_r:

https://sourceware.org/ml/gdb-patches/2015-04/msg00266.html

Fix that by importing the strtok_r gnulib module.

gdb/ChangeLog:
2015-04-08 Pedro Alves <palves@redhat.com>

* gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add strtok_r.
* gnulib/Makefile.in (aclocal_m4_deps): Add import/m4/strtok_r.m4.
* gnulib/configure, gnulib/config.in, gnulib/aclocal.m4: Regenerate.
* gnulib/import/Makefile.am: Update.
* gnulib/import/Makefile.in: Update.
* gnulib/import/m4/gnulib-cache.m4: Update.
* gnulib/import/m4/gnulib-comp.m4: Update.
* gnulib/import/m4/strtok_r.m4: New file.
* gnulib/import/strtok_r.c: New file.
