Great, one thing less to worry about.

Ups, I merged two issues above. First is option --libdir, which has
a value of ${PREFIX}/lib/gcc/${CONFIGURE_TARGET}/${PORTVERSION}. This
is a problem for Ada, as libraries get installed into very deep and
odd looking path. Setting this option to ${PREFIX}/lib doesn't seem to
change anything for C and C++, but it helps Ada. Don't know about the
other compilers though.
Binaries are another problem, as program name transformation does not
currently work for Ada. I'll see what I can do about it.

galaxian-4.1.2 :))

I didn't think about that. Look, I'd like to have Ada in GCC ports
in the end. There already is a FreeBSD port of GPL-ed GNAT, based on
GCC sources and patches prepared by AdaCore. Would it be acceptable if
I prepare ports named like gcc_gnatXY? These would mostly be copies of
gccXY ports with Ada included, and when matured, they could be merged
into GCC ports?
