[GEMPAK #VNL-434404]: GEMPAK - Using g77 to link to gempak libraries

Martin,

Check the iacss (aka iflno) file access number you are passing to the gd_rdat 
routine.
You may be stepping on it inadvertantly and the "-4" response is the file number
is not open.

Often, Solaris is more tolerant to running past an array bounds due to the way
memory is positioned, where gcc/g77 shows the problems first.

> IB/cgemlib.a -fno-second-underscore
