NO.  I disagree strongly with most of the statements.

First, GCC should be bootstrappable with GCC or the HP compilers (bundled
or unbundled).

Second, I do *not* recommend using the binaries at hpux.cs.utah.edu.

Third, you should be able to use hpux11 (32 bit mode) without using a
binutils snapshot.

Fourth, you do not need bison, if you ever need bison to build a release,
then there's a bug somewhere.

There shouldn't be any problems with alloca.  I've been developing on this
platform for years and it should just work.

I do not encourage an explicit path to the assembler.  Never have, never
will.  There are better ways to solve that problem.
