Subject Re: [PATCH] apr_get_groupname
Date Fri, 02 Feb 2001 21:26:41 GMT

Ok, I'm an idiot.  I completely missed the implementation in groupinfo.c.

I was having some problems with undefined symbols in httpd because the linker
wasn't pulling that symbol in from aprlib.a, but I guess that was fixed a
couple of days ago.
