You meant --with-ssl-dir?

Yes, in the same way it's done with the other usual support libs.  You
want to add a AC_ARG_WITH(ssl-includes) and (ssl-libs) which overwrite
ac_ssl_{includes,libraries) in admin/acinclude.m4.in.  Although I think
3.0.x is more or less dead.

Yes, that test is very supoptimal.  You are free to create a better one.
That better test could look at the given compiler (for any -n32 or
whatever flags), or better yet would inspect an object file produced by
it from a trivial source to see if it's o32 (then barf ;-), n32 or n64.
In the latter case and if /lib64 exists default to .../lib64 suffixes for
the usual libdirs.

It's not only possible, it is even done for some distributions which are
64bit only (ia64, alpha, mips and hammer for instance).


Ciao,
