The follow patch will allow binds to a static zlib, but it's not entirely portable.
I'm wondering which ac/libtool guru might point me at:
1. a way to ADD to the objs list of just THIS module, instead of having
to second-guess the name of the mod_deflate object.
2. the portable 'shared library type', as opposed to my test -f libz.s? below
3. the way to modify APR_ADDTO(LIBS, [-lz]) where it -lz would be added
only to the list given to the mod_deflate link, instead of all objects (even
the core httpsd and support modules, before rbb's patch yesterday!.)
TIA
