[Bug fortran/33942] New: FreeBSD gfortran interprets an external function as a library function?

["michael dot a dot richmond at nasa dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

When I compile the program listed below using the FreeBSD version of gfortran I
get the message:

/var/tmp//ccTgf1if.o(.text+0x1f): In function `MAIN__':
: undefined reference to `tgammaf'
collect2: ld returned 1 exit status

I noticed this problem in the October 26 snapshot of gfortran. I don't recall
whether it occurs in earlier versions.

I do not see this problem in Linux.

The problem goes away if I insert the declaration "EXTERNAL gamma" into the
main program.

PROGRAM pgamma
y = gamma(x)
END PROGRAM pgamma

FUNCTION gamma(x)
gamma = 0.0
END FUNCTION gamma
