Janne,

With your patch and enable-maintainer-mode, I see multiple failures.
These are all due to undefined references to the following symbols
`csqrtf', `csqrt', `_gfortran_pow_i16_i16', `cosl', and `cpowf' on
amd64-*-freebsd.  I believe FX alerted you to the problem with
_gfortran_pow_i16_i16 missing in the gfortran.map.  csqrtf, csqrt,
and `cpowf' are defined in c99_functions.c.  I have no idea why
I'm picking up cosl, which is not in my libm.
