You don't need to do a lot of those steps.

You might want to install other such patches, also makesure you install 
the patches in 64 bit mode (it's not default).

B6733AA B.11.00.10 DCE/9000 Kernel Threads Support
PHKL_14750 1.0 Fix pthread_cond_timedwait(3T) error return 
PHKL_17935 1.0 libpthreads cumulative patch

personally I would build binutils first with the native compiler, then 
build gcc. Then perhaps rebuild the binutils with gcc but it hardly 
matters. Just in cae you do have gnu ld laying around I would do --
without-gnu-ld as it does  break unexpectedly on 64 bit shared librarys.
(building ACE for example)

You wouldn't really need to build the compiler again, there is no need 
for it. The stage 1 compiler builds the stage 2 compiler so there is 
nothing to be gained here at all. If you are worried about as build 
binutils before hand.. the as exec may be a little different but it *
will* output exactly the same code as before.

As a matter of note this is my gcc -v output:
Configured with: ../configure --prefix=/home/users/daviesr/local --
enable-shared=libstdc++ --with-gnu-as --enable-threads=posix --enable-
languages=c++ --enable-version-specific-runtime-libs --with-as=/home/
users/daviesr/local/bin/as : (reconfigured) ../configure --prefix=/home/
users/daviesr/local --enable-shared=libstdc++ --with-gnu-as --enable-
threads=posix --enable-languages=c++,objc --enable-version-specific-
runtime-libs --with-as=/home/users/daviesr/local/bin/as
Thread model: posix
gcc version 3.0

One point though, building the Standard C++ Library is likely to fail 
on the first pass, ltconfig is broken for some reason I can't quite 
work out so you might have to manually add something to the appropriate 
config.cache file to force it to work.

install

It's 64 bit, 2.95.2 didn't support HP-UX 11 afair, but gcc-3.0 does 
because it's 64 bits. 

Still my word is not definitive, just being a good friday samariten.
