> Ahh, you are correct.  Success!  What does this mean?
I found this in the cf77 release notes, not sure if it means anything to us at this point.

Linking with gcc, g++ or g77:
This release ships with its own updated linker (ld) that can interpret DWARF 3. If you link cf77generated code using the gcc, g++, or g77 commands, they should be directed to use this alternativeld. This may be done by setting the COMPILER_PATH environment variable to one of the followingvalues:COMPILER_PATH=/usr/ccs/release/7.2/lib_ia32COMPILER_PATH=/usr/ccs/release/7.2/lib_amd64for 32-bit Pentium code or 64-bit AMD64 code, respectively. It important that the correct path bechosen.To make the COMPILER_PATH effective for the duration of a shell invocation, it can be exported:export COMPILER_PATH=...Or the variable may be set for a single invocation:COMPILER_PATH=... gcc ...If the COMPILER_PATH environment variable is omitted, the default system linker will be used; it willwork on correct programs, but error diagnostics may be inaccurate.The cf77 command will use the alternative ld without requiring the user to set the COMPILER_PATHenvironment variable.
