Look at how erfc or the bessel functions are implemented.  We 
do not use MPFR.  We map the functions to libm if the functions
are available.

kargl[202] cd gcc/gcc41/gcc/fortran
kargl[203] grep -i erfc *
gfortran.h
intrinsic.c
intrinsic.texi
mathbuiltins.def


Look at the these files
kargl[205] cd gcc/gcc41/libgfortran
kargl[206] find . -type f | xargs grep -i erfc
config.h.in
configure.ac
./intrinsics/erf.c
