Bug reports should be filed for these two problems.  Do you have
PHCO_20721 and PHCO_26158 installed?  Locale might the behavior
of awk in generating options.h.

Personally, I always use GNU tools (e.g., gawk, sed, make, texinfo)
for my builds as I find this avoids a lot of problems.

Regarding the use of pthreads, that's strange.  Without --disable-threads,
GCC should use DCE threads on hpux10.  GCC definitely knows about the
threads available in HP-UX 10.  See for example, gthr-dce.h.

I should note that libjava isn't supported on HP-UX 10.20.  Without
libjava, building the java language is largely just an extra test
of the bootstrap process.

GCC 4.2.0 will be the first release supporting libjava on PA-RISC HP-UX.
Currently, this only works with the 32-bit HP-UX 11 port.  We don't yet
have a 64-bit port of libffi.  It's needed to build libjava.  Also,
boehm-gc and libjava need POSIX threads for full functionality, and
the don't support DCE threads.  For this reason, the toplevel configure
file disables building libjava on HP-UX 10.  These libraries will build
without threads and it's possible that this will work under HP-UX 10,
but I haven't had a chance to test this.
