Kevin,

I posted the updated files (3 of them) in:
http://my.unidata.ucar.edu/content/software/gempak/download/patches/dcgrib2_update.tar.gz

the tarfile contains:
GEMPAK5.7.4/unidata/ldmbridge/dcgrib2/decode_g2pdt.c
GEMPAK5.7.4/gempak/tables/grid/g2cord.tbl
GEMPAK5.7.4/gempak/tables/grid/g2vars.tbl
