svn commit: r730926 - /httpd/httpd/trunk/acinclude.m4

[je...@apache.org]

Author: jerenkrantz
Date: Fri Jan  2 22:40:32 2009
New Revision: 730926

URL: http://svn.apache.org/viewvc?rev=730926&view=rev
Log:
Make OpenSSL pkg-config usage consistent so that we don't run the early
configure checks against a /usr installed OpenSSL and then link against
a different pkg-config installed OpenSSL.

(Hint: Try with Mac OS X with MacPorts's OpenSSL or FreeBSD w/OpenSSL ports.)

* acinclude.m4
  (APACHE_CHECK_SSL_TOOLKIT): Load in pkg-config variables first before doing
  any OpenSSL checks so that we don't clobber things later.
