Good C Debuggers for 4GL?

I was wondering if anyone knew of a C debugger that can be used with C code generated by the c4gl program. In order for the debugger to be useful, it would have to be able to reference the original 4GL code that corresponded to the current execution state of the C program. Has anyone heard/know of such a debugger?
