Subject: Eliminate ap_config.h's checks when using autoconf. Now, ap_ac_config.h
X-Git-Tag: 1.3.10~135
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=04c494c2b5175d094185f00304a17a837c44d810;p=apache

Eliminate ap_config.h's checks when using autoconf. Now, ap_ac_config.h
is used instead, and autoconf's configure script will check for
everything else.
