> 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.
