True. But even if written in C, you need to play with RMS features to handle both:

$ cc /list [somedir]source.c

vs

$ cc [somedir]source.c /list

correctly although you might be able to dig the info from stat() and use the VMS-extensions to fopen() for default file name (ie "dna=") but there isn't an extension for related filenames.  You could fallback to a "acc=" callback, but then you are back in the RMS world.
