See also PR 47648 (same issue for FreeBSD on ia64; contrary to NetBSD/this PR
it works on x86-64).
For FreeBSD/ia64 the problem is that _U_Q* are missing, though it is unclear
whether NetBSD's libc or GCC's libgcc should provide those.
Cf. also bug 47649 comment 5.

--disable-libquadmath-support was enough to build.
However gfortran test results are pretty poor:
=== gfortran Summary ===
# of expected passes 24669
# of unexpected failures 11625
# of expected failures 41
# of unresolved testcases 40
# of unsupported tests 622
Lots of failures seems to be excess warning for cabsf() and cabs():

Could you try whether using the patch in attachment 23341 (from PR 47648)
allows you to build GCC without --disable-libquadmath-support? It copies the
configure check from libquadmath to libgfortran.
> However gfortran test results are pretty poor:
> warning: warning: reference to compatibility cabsf()
Looks as if complex numbers are not well supported; I do not quite see why the
warning is generated - and for which library.
(libgfortran contains at libgfortran/intrinsics/c99_functions.c a fall-back
implementation for cabsf, which uses hypotf, which uses (if not present)
hypot.)

Tobias, the patch you mentionned did allow bootstrap with c,fortran and without
disabling libquadmath for gcc version 4.6.0 20110212 (experimental) [trunk
revision 170072] (GCC).
Feel free to ask for a farm account this will be much more efficient than going
through me for each test, instructions here:

will deactivate fortran in my future builds because otherwise the

> warning: warning: reference to compatibility cabsf()
That seems to be a warning generated by NetBSD's libm, cf.
http://mirror.leaseweb.com/NetBSD/NetBSD-release-5-0/src/lib/libm/compat/compat_cabsf.c
That file contains:
float cabsf __P((struct complex));
__warn_references(cabsf, "warning: reference to compatibility cabsf()");
float
cabsf(struct complex z)
{
return hypotf(z.x, z.y);
}
Which causes the warning. The __warn_references is defined in <sys/cdefs.h>.
Thus, you could also try to silence the warning. hypot(f) should be give an
equivalent result to cabs(f) - thus I do not understand why there is a warning
at the first place. (Depending, of course, on the quality of the hypot(f)
implementation.)
As the warning is due to NetBSD itself and as the quadmath_weak.h issue is
solved, I close this PR.
It would be nice if one could silence the warning - and again build with
Fortran support.
