I find it easiest just to invoke the compiler proper.
$ echo $cobol1
[...]/build/gcc/cobol1
$ gdb --args $cobol1 -oo foo.cbl
That sets the compiler driver aside, and lets me work directly on the
compiler.
Of course, I'm concerned with just one language, and just one
compiler. If your concern crosses languages, I'd imagine the -wrapper
technique would be easier.
