Here's my 2 cents worth on the HPUX ports.

As of 3.3, the 64-bit port has essentially reached equivalence in
features and hopefully reliability with the 32-bit port.  Thus, as
long as 3.3 can be built with HP's K&R compiler, then I believe it
provides a suitable starting point for building later versions if
trouble develops.  There is a complete toolkit for the 32-bit port,
so in theory it can be built using a cross compiler.

HP and the HPUX porting centre make binaries available.  Thus, HPUX
shouldn't be a show stopper in ANSIfying GCC.  Indeed, dropping K&R
support might nudge HP into making their ANSI compiler freely available.

The parisc-linux system is coming along nicely.  I believe that in
the near future it will be the OS of choice for running free software
and HPUX will become less relevant.

FWIW, I am pragmatic about the benefits of dropping the capability to
perform K&R bootstraps.  The bundled HP compiler is small and fast.
There is something to be said for a light-weight implementation.  The
error checking in K&R compilers is somewhat different and sometimes it
issues that should be fixed.

With the patch below, 3.4 appears to building successfully in 64-bit
mode with the bundled compiler.
