According to John Miller:

I wrote earlier about problems with gpc making on solaris 2.5 (SunOS 5.5).

I'm wanting to run this same program on a DEC alpha, a Sun ULTRA, an HP9000 K370, and some kind of IBM box.

[...]

Unfortunately, I have no experience with these machines, and I can't read off anything I understand from the error messages. :-( Maybe you can use one of the binaries we are providing at ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/binary? Otherwise, I recommend to try again with a recent beta version of GPC. The compilation/installation method has changed violently - in part for solving such incomatibility problems.
