In my experiences, it has been somewhat tricky to compile Polyorb with
various GNAT versions. Polyorb-gpl-2007 + gnat-gpl-2007 is probably the
safest pair.

You can compile some versions of Polyorb with GCC 4.[23], but usually
only the corba personality compiles.

Another issue is the GNAT memory usage. For example, when compiling
corba-repository_root-abstractinterfacedef-skel.adb or
corba-repository_root-helper.adb GNAT uses over 1G memory. Some systems
have hard limit of 1G (OpenBSD/x86 for example), so one needs to turn
off optimization for those files.

Yeah, testing gnat-gpl+polyorb-gpl on Linux will make your life much
easier. Personally, I use OpenBSD and have been able to compile Polyorb
on it, so it should be possible on OS X also, but it probably takes
few iterations with different versions of GNAT and Polyorb and a lot
of patience. :)

Here is my patch to turn off optimizations for the files mentioned
above. It is something like 3-6 months old, so I am not 100% does
it work the the current SVN sources. (You need to regen autotools/
configure scripts after applying the patch.)
