Yes, but the problem is even tougher, since awk allows multiple source
files (multiple -f options). Additionally, gawk provides file inclusion
and path searching for -f, -i, and @include.  But in the end all these
files combine into a single program.  

The information can be recovered manually, for command line files,
by looking at PROCINFO["argv"] and the various search path environment
variables, but that still doesn't cover @include files. (See the igawk
program for an example of how it might work.)
