>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.
