Gempak users, I have repackaged the GEMPAK 5.6.h distribution tar file to include a target for building under Solaris using gcc/g77. The updated distribution provides a flag in the Gemenviron script USEGCC_SOL. If the line is uncommented, then the build will attempt to use the gcc/g77 build environment. The resulting $GEMEXE directory will be $NAWIPS/bin/sol_gcc and will be appended to PATH instead of the usual $NAWIPS/bin/sol. In addition to setting the NA_OS environmental variable in Gemenviron, the following files have been updated/created: $CONFIGDIR/Makeinc.sol_gcc $GEMPAK/include/MCHPRM.SunOS.gcc $GEMPAK/include/SunOS.gcc/MCHPRM.PRM $GARPHOME/config/platform/Makeinc.sol_gcc $NAWIPS/unidata/ldmbridge/dcprof/Makefile Steve Chiswell
