I use the following options for PCRE:
--enable-utf --disable-cpp --disable-shared
Since my apache is selfcontained and built using a build script i didn't 
see any reason to make pcre shared.  --disable-cpp is because apache 
isn't c++ so no need for cpp support.  enable-utf is probably not 
necessary since most of the regex stuff in apache is on urls which 
should be escaped but i figured why not.

-fPIC is not necessary for openssl, at least on Linux.  the shared 
Configure option takes care of that for you.
