OK. Just to double-check, can you try to remove the "b"s anyway
in function 'file_open_mode' in $GOBO/tool/gec/runtime/c/eif_file.c
and recompile your program (no need to recompile gec itself)?
Perhaps the "compatibility" goes up to the point where filenames
are considered case-insensitive. Who knows.
