Huh? My reading of the sources of FreeBSD


and NetBSD


is just the opposite: Whatever may the initial value of __progname be,
it is erased when setprogname is called.

Which is also reasonable: you want to allow an application to override
system behaviour, not the other way around.

And LibGW32C-0.4 (see http://gnuwin32.sourceforge.net/packages/libgw32c.htm)
has apparently renamed this function to getprogname(). While _not_ providing
a setprogname().

What I presented was only a sketch. Let's discuss details when I show
the real code.

It's missing the removal of the dirname, of "-" and of "lt-". Also,
it lacks a setprogname() function if the system provides getprogname()
but not setprogname().
