	FreeBSD 4-STABLE.

>Description:

        libg2c uses mktemp() and tempnam() which causes all Fortran
programs linked with it to issue a warning upon linking and of course
makes the resulting binaries susceptible to problems of mktemp().

>How-To-Repeat:

        Compile and link any Fortran program with FreeBSD 4. I do not
know if this applies to CURRENT, but I suspect it does.

>Fix:

        Apply the following patch in the /usr/src/contrib/libf2c/libI77
subdirectory.
