[GEMPAK #TFE-467943]: GEMPAK - problem with linking to gemlib.a

Ying,

> ermmsg.o(.text+0x664): undefined reference to `css_gtim_'

You need to add cgemlib.a to your link line libraries.

The er_wmsg_ routine is calling the css_gtim function from the
cgemlib.a library.

The comment about using the gcc linker is based on how Fotran routines
can call C routines and whether the linker is looking for the "_"
character following the subroutine name. As long as your link line can
resolve the dependencies, you can use other linkers.
