Does the existing progname module do what you want?

This is too short-sighted.  The C standard changes, and also some GNU
programs assume behavior that is supplied by GNU implementations of
the C99 standard.  It's not unreasonable for an application to
substitute its own implementation of malloc, so long as this
implementation also conforms to the C standard.  Any code that is
intended to be portable should work with such an malloc.

I'm afraid that I see some flaws (the #defines will screw up standard
system headers).  They might be worked around if someone found the time...

Yes, that's it.

It's quite a big performance improvement in coreutils, if memory

Your other points also deserve further thought....
