The following applies to the March 7 snapshot under FreeBSD. I haven't tested
it on other platforms. When I compile and link the following program:
PROGRAM test_exp
x = exp(1.0)
END PROGRAM test_exp
I get the message:
/usr/home/mrichmond/irun/bin/../lib/gcc/i386-unknown-freebsd7.0/4.4.0/../../../libgfortran.so:
undefined reference to `expl'
collect2: ld returned 1 exit status

------- Comment #1 from kargl at gcc dot gnu dot org 2008-03-11 02:22 -------
This is caused by the recent addition of erfc and erf intrinsics. You'll
need to ask FX to fix the problem. The guilty diff is
http://gcc.gnu.org/ml/fortran/2008-02/msg00318/2008-libgfortran.diff
which unilateral defined EXP(x) as expl().

There's one good thing in FreeBSD: it sure helps finding any reference to a C99
long double function that is not protected by a autoconf macro :)
Can you please try the following patch and tell me whether it helps?
