Subject: AC_PROG_MKDIR_P: reduce macro output size
X-Git-Tag: v2.69b~96
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=acb200444395b8108b42dfacd54dabd02d966bd3;p=thirdparty%2Fautoconf.git

AC_PROG_MKDIR_P: reduce macro output size

Merging two case globs into one gives slightly smaller files and
less time spent in shell globbing on systems that lack GNU mkdir.

* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Combine two GNU cases.
