That should work.  But it seems this __progname issue could be cleaned
up by defining the variable in main() files if needed:

#ifndef HAVE___PROGNAME
const char *__progname = "foo";
#endif

then declaring it (no ifdefs) if it's referenced:

extern const char *__progname;

This gets us closer to OpenBSD's tree with fewer ifdefs.

I'll do this patch unless someone points out what it will break :)
