I don't worry about official releases compiling without errors or under
maintainer mode - they're already out there, so there's nothing we can do to
change the compile warnings or errors that exist.
but you're right, I wasn't thinking that the issue could be the extra flags
maintainer mode added. I was just thinking it was the difference between my
old (pre drive failure) fc1 install where everything was fine and my new
(post new drive) fc3 install.

yeah, sounds like it. mod_perl won't even build for me because httpd -l
dumps core
$ gdb /apache/2.0.47/prefork/perl-5.8.7/bin/httpd
(gdb) run -l
...

somewhat, but not entirely. the things that concern me most are macros,
constants, subroutines, etc that exist only in later versions that somehow
creep into our codebase inadvertently, making it difficult or impossible to
compile or run mod_perl against older versions of httpd. so, in that sense
getting httpd to compile so we can "test" against it is a good thing.
so, thanks for the link :)

Yup, this is the specific bug I mentioned. If using an old version of
gcc is not practical you can apply the patches to fix it in APR:
http://svn.apache.org/viewcvs.cgi?rev=58984&view=rev
though this somewhat erodes the value of testing against "2.0.47" or
whatever.

Yeah I figured.

Yep thats the one!

ports and packages on FreeBSD do not. There are however options not on by default to enable them
in ports. The ports Makefiles are used to build the pacakges, but again, this option is not on for that.
