Builds fine with GCC.

While here, remove ia64 support.

Upgrade from 5f1 to 5f2.

The bad news:

	1. gcc is still required -- clang can build the binaries, but
	   some self-tests will fail, unless all optimization was
           disabled. This is, probably, due to some suspect code in
           bytenumb.c -- would be good to investigate.
	2. Building this port in parallel is still not possible -- the
	   Makefile is too convoluted and same sources are recompiled
	   multiple times with different #defines set.

The good news:

	1. Resolve a large number of warnings.
	2. Fix build on ia64 and sparc64 (tested on pluto and flame
           respectively). Other platforms (alpha, powerpc?) have a
	   better chance of working now...
