Gack.

The realloc((char*)0, size) thing was bad enough. What's this all
about?

Stuff like this just makes it hard to port ANSII programs to
old systems. Also makes it harder to convert an old system to ANSII.
I can't think of any good reason to add such a silly spec. What am I
missing?

Can anyone suggest a legitimate reason why they would want to do such
a thing?
