This imports the "pathmax" gnulib module, making PATH_MAX always available on systems that have the notion of a constant max path limit (i.e., practically everywhere except the Hurd), along with fixing a couple broken systems --- see pathmax.h in the patch. This means we can normalize on PATH_MAX throughout the tree (instead of some places using MAXPATHLEN, or defining fallback constants ourselves). This is the just the importing step. gdb/ 2013-07-01 Pedro Alves <palves@redhat.com> * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add pathmax. * gnulib/Makefile.in (aclocal_m4_deps): Add import/m4/pathmax.m4. * gnulib/aclocal.m4: Regenerate. * gnulib/config.in: Regenerate. * gnulib/configure: Regenerate. * gnulib/import/pathmax.h: New file. * gnulib/import/Makefile.am: Regenerate. * gnulib/import/Makefile.in: Regenerate. * gnulib/import/m4/gnulib-cache.m4: Regenerate. * gnulib/import/m4/gnulib-comp.m4: Regenerate. * gnulib/import/m4/pathmax.m4: New file.
