Ah, well there is the problem: you are (in effect) assuming that
if stdlib.h defines random() on your platform, then it does so on
everyone's platform. If that were true, we'd not need port/random.c...
I think your script ought to be set up to ignore system headers
completely, and only look at our own headers to determine which
symbols are defined where.
In theory, only config.h and c.h should contain any substitutes for
system-header symbols, so if you explicitly exclude those two from
removal then there should be no portability issue. But I'd be
happier if you changed the script so that its decisions are not
affected by the contents of system headers.
