Tried using the native compiler with "gmake -j", but it never returns 
after launching the first job.  For example, with "-j 4" this happens:

configure: summary of build options:

   Version:           GNU MP 6.1.2
   Host type:         itanium2-hp-hpux11.31
   ABI:               32
   Install prefix:
   Compiler:          /opt/aCC/bin/cc -w
   Static libraries:  yes
   Shared libraries:  no

/opt/aCC/bin/cc -w `test -f 'gen-fac.c' || echo './'`gen-fac.c -o gen-fac
/opt/aCC/bin/cc -w `test -f 'gen-fib.c' || echo './'`gen-fib.c -o gen-fib
/opt/aCC/bin/cc -w `test -f 'gen-bases.c' || echo './'`gen-bases.c -o 
gen-bases -lm
/opt/aCC/bin/cc -w `test -f 'gen-trialdivtab.c' || echo 
'./'`gen-trialdivtab.c -o gen-trialdivtab -lm

And nothing comes back...  The same for zlib, so it's nothing special to 
GMP.  While with native make we can build with more threads to speed up 
the builds, and only with GMP we are limited to 2 threads, because of 
the reported issue.

Have you had more luck with the native HP-UX compiler and GNU make for 
parallel builds?
