After updating trunk to include the above mentioned patch,
x86_64-*-freebsd built without a problem.  All of the 
Fortran codes in the PR audit trail ran and gave the
expected output.  The c code gave various, interesting
output as might be expected because FreeBSD's libc lacks
the printf hooks.  Jakub, thanks for fixing this issue.
