Can you try the head of the GCC 4.9 branch (or a recent snapshot)?

I attempted to build the gcc-4.9.0 release, and it bombs out in libquadmath:

gmake[4]: Leaving directory
`/nfshomes/platzk/gnu/gcc-build/4.9.0/hppa2.0w-hp-hpux11.23/libffi/include'
Making all in testsuite
In file included from ../../../../gcc-4.9.0/libquadmath/math/x2y2m1q.c:19:0:
../../../../gcc-4.9.0/libquadmath/quadmath-imp.h:55:3: error: #error "No way!"
 # error "No way!"


This appears to occur when there is no UINT_64 detected.  This is on a PA-RISC
2.0 system, so the "unsigned long long" data type is available.

I am also running into this on HP-UX 11.23 on PA-RISC. I've started with HP's
distribution of GCC 4.7.1 and have attempted to build 4.7.4, 4.8.5, and 4.9.4
and have gotten this same error. I can build 4.9.4 successfully if I disable
libquadmath, but trying to build 4.9.4 with it enabled with the no-quadmath
4.9.4 build results in the same error.

I'm configuring GCC as follows:
../../sources/gcc-4.9.4/configure --prefix=/usr/util/gcc/gcc-4.9.4 --disable
-nls --enable-languages=c,c++ --with-gmp=/usr/util/gcc/gmp-6.1.0
--with-mpfr=/us
r/util/gcc/mpfr-3.1.6 --with-mpc=/usr/util/gcc/mpc-1.0.3 --without-gnu-ld
--with
-gnu-as --with-as=/usr/util/gcc/binutils-2.25/bin/as
CONFIG_SHELL=/usr/util/bin/
bash AWK=/usr/util/bin/awk SED=/usr/util/bin/sed

For anyone finding this in the future, I'm guessing 32-bit builds of GCC on
HP-UX+PA-RISC were just broken for a while. Building 5.5.0 with libquadmath
enabled worked fine.
