I am not on the steering committee.  But I am a user of GCC.

I am using GCC on HP-UX 11.11 quite successfully.  I am using the
following versions.

  binutils-2.14
  gcc-3.3.2

First build and install binutils.  Because the names are the same as
existing native programs I use a program prefix.  'as' becomes 'gas'.
Also, I do not want to use the shared libraries so I disable them.

  binutils-2.14

  ./configure \
    --prefix=/usr \
    --mandir=\${prefix}/share/man \
    --infodir=\${prefix}/share/info \
    --program-prefix=g \
    --disable-shared

After GNU binutils has been installed then build and install gcc.  I
want to keep multiple versions of gcc on the system at the same time.
Therefore I use a program suffix of -3.3 in this case and version
specific libraries.  I am only needing C and C++ so I specify only
those.  I need to use the libstdc++.a files in perl shared libraries
and so I compile with -fPIC.

  gcc-3.3.2

  LIBCFLAGS="-O2" LIBCXXFLAGS="-O2 -fno-implicit-templates" \
    ./configure \
    --prefix=/usr \
    --mandir=\${prefix}/share/man \
    --infodir=\${prefix}/share/info \
    --program-suffix=-3.3 \
    --with-as=/usr/bin/gas \
    --with-gnu-as \
    --enable-version-specific-runtime-libs \
    --enable-languages=c,c++ \
    --enable-cxx-flags='-fPIC'

The GCC build on HP-UX uses the native header files.  In most cases
that is fine.  But in some cases this can create spurious errors.  The
header <ctypes.h> is one of those.  This is the only patch I need at
this time to compile standard C code.

Change this:

  #define isalpha(__c) (__SB_masks ? (int)__SB_masks[__c] & _ISALPHA

To this:

  #define isalpha(__c) (__SB_masks ? (int)__SB_masks[(int)__c] & _ISALPHA

  sed '/__SB_masks.__c/s/__c]/(int)__c]/' ./gcc/include/ctype.h \
    > ./gcc/include/ctype.h.new
  mv ./gcc/include/ctype.h.new ./gcc/include/ctype.h

Of course you may need a different set of options.  You may want to
install in /usr/local instead of /usr for example.  These are just the
options and configuration that I am using.  YMMV.
