It was I who 'tried' to compile on HPUX and run the regression tests. I
would be happy to help porting boost to HPUX. We've given up for the
exact reasons Dave mentions: ICE's the whole time although isolating the
problems in a small sample is very hard. And behaving differently on a
big source file compared to a small source file (using the same
features) reveals (to me) that the compiler is of very low quality. So
trying to isolate problem situations is hard and the aCC people seem not
very interested either so I figured that it was not worth the effort.

Now is you say that you have good experience and you want to help to
push the limits of aCC and you think we can get good response from HP,
I'm willing to give it another go !!!

But I suggest you install it from a .depot file because compiling gcc on
HPUX might be very hard.
