Re: cvs commit: jakarta-tomcat-connectors/jk/native2/common jk_md5.c
Posted by Kurt Miller <tr...@optonline.net>.
While testing the apr m4 patches I'm working on, I noticed that this commit
has introduced a dependency on apr-util (via apr_md5.h). I guess that means
./configure will need --with-apr-util etc. etc. to support apache13. Yes?
