You can work around this by configuring MPFR with > --disable-thread-safe We are building GCC against mpfr-3.1.6 but MPFR wasn't a difficult build on HP-UX/IA. We are building with the HP C compiler though. The MPFR testsuite passed all but one test which was a PASS. And, ./configure shows -DMPFR_USE_THREAD_SAFE=1.
