GCC 3.0 and up support HP-UX 11. You must use GNU binutils 2.11 or above on
this platform. Thread support is not currently implemented for this

See @uref{http://gcc.gnu.org/ml/gcc-prs/2002-01/msg00551.html}
GCC 3.0 and up support HP-UX 11. On 64-bit capable systems, there
are two distinct ports. The @samp{hppa2.0w-hp-hpux11*} port generates
code for the 32-bit pa-risc runtime architecture. It uses the HP
linker and is currently the default selected by config.guess. The
optional @samp{hppa64-hp-hpux11*} port generates 64-bit code for the
pa-risc 2.0 architecture. It must be explicitly selected using the
@samp{--host=hppa64-hp-hpux11*} configure option. Different prefixes
must be used if both ports are to be installed on the same system.
You must use GNU binutils 2.11 or above with the 32-bit port. Thread
support is not currently implemented, so @option{--enable-threads} does
not work. See @uref{http://gcc.gnu.org/ml/gcc-prs/2002-01/msg00551.html}
and @uref{http://gcc.gnu.org/ml/gcc-bugs/2002-01/msg00663.html}.
GCC 2.95.x is not supported under HP-UX 11 and cannot be used to
compile GCC 3.0 and up. Refer to @uref{binaries.html,,binaries} for
information about obtaining precompiled GCC binaries for HP-UX.
GNU binutils 2.13 or later is recommended with the 64-bit port.
The HP assembler is not supported. It is @emph{highly} recommended
that the GNU linker be used as well. Either binutils must be built
prior to gcc, or a binary distribution of gcc or binutils must be
obtained for the initial builds. When starting with a HP compiler,
it is preferable to use the ANSI compiler as the bundled compiler
only supports traditional C. Bootstrapping with the bundled compiler
is tested infrequently and problems often arise because of the subtle
differences in semantics between traditional and ISO C. There also
have been problems reported with various binary distributions. This
port still is undergoing significant development.
