Subject: * acgeneral.m4 (AC_PROVIDE): Use `m4_define', not `define'.
X-Git-Tag: autoconf-2.50~1189
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3986defac7a3cbabeae7a37cadfe7d4bdcfcc841;p=thirdparty%2Fautoconf.git

* acgeneral.m4 (AC_PROVIDE): Use `m4_define', not `define'.
Because of the namespace machinery this change makes `autoconf'
about four times faster on complex `configure.in's.
