Regarding this PR (PR 47649) and also regarding PR 47648:
Is libquadmath actually build? In either case: Can you show how the configure
output of libquadmath looks like?
I assume you did not configure with --disable-libquadmath nor with
--disable-libquadmath-support - or did you?

no, I didn't use any configure options,
just a default build from ports.

I think the important hunk is:
configure:12340: checking whether __float128 is supported
...
/var/tmp//cciKxWc5.o: In function `foo':
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:35:
undefined reference to `_U_Qfdiv'
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:39:
undefined reference to `__divtc3'
/var/tmp//cciKxWc5.o: In function `bar':
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:44:
undefined reference to `_U_Qfmpy'
which means the ia64 __float128 support is not in a good shape, either just on
freebsd, but maybe on anything but hpux. It is unclear whether _U_Q* are meant
to be provided by ia64 libgcc or libc.

To my knowledge, libquadmath works on IA64 Linux [1-2] (which is contrary to
FreeBSD GLIBC based) and also on HPUX, though there it is not used by gfortran
[3]. It also works on x86-64-FreeBSD thus it looks as if only FreeBSD on IA64
is affected - maybe also other non-Linux, non-HPUX based operating systems on
IA64.

[3] http://gcc.gnu.org/ml/gcc-testresults/2011-02/msg00858.html though as on
HPUX "long double" is as wide as __float128, gfortran uses calls to the
long-double version for REAL(16). However, I recall that libquadmath works.

BTW, the error mentioned in #c0 doesn't look like from something performed by
make install of gcc itself, are you sure it isn't something that FreeBSD ports
has around gcc make install and that just expects libquadmath will be supported
on all targets? That would be a FreeBSD ports bug, rather than a gcc bug.

Yes, this is related to the lang/gcc46 port assuming libquadmath
being working (which it does on all sane architectures). I'll
provide a suggested patch Anton for testing outside of this bug.
I suggest to repurpose this bug to identify why and possibly fix
_why_ this does not work on FreeBSD/ia64.

Actually, let me take this back. This very bug probably should
be closed (I'll address it on the FreeBSD side), but #47648 looks
like a genuine one for Tobias or Jakub?

This was an issue with the FreeBSD Ports Collection (on ia64 and sparc64)
which I have addressed on that end.
