I don`t now such a definition (but looking for it too)!

We use SunOS 4.1 (Sparc) and gcc (1.40). If you want to use dbxtool (dbx),
you have to change and recompile gcc.c: in function "process_command(argc, argv)"
all "input-file-names (infiles[..])" and "output-file-names (-o <..>)" should be
extended to full path names via the "realpath" system call (for output-files
the error ENOENT has to be ignored). Without this modification, the debugger will
not be able to find the sources if your current working directory does not
contain the source files of the program to debug.
