I don't have access to other compilers than GNAT, but for GNAT (GPL and
FSF) I do try to support Linux and Windows/Cygwin as well as Mac OS X.

I've put a small writeup from the user point of view at [1]. This is a
work in progress.

One thing I personally find helpful is to install alongside the
compiler, because I have more than one installed (at the moment, GCC
4.6.0 and GNAT GPL 2011). The source may be compiler-agnostic, but the
object and ali files certainly aren't. Also, this saves the bother of
specifying the ADA_PROJECT_PATH.

There are at least 2 ways of doing this with GNAT. One is the way that
GNAT GPL and FSF GCC use, which is that the GPR is found in
$prefix/lib/gnat/, source in $prefix/include/$package/ and objects in
$prefix/lib/$package/. The other is the way that Debian uses (see the
Policy).
