The current implementation of <assert.h> causes warnings when
using compile-time expressions that evaluate to true (like `assert(1);')
in combination with the gcc flags `-Wall -pedantic'.

Below is my new version of assert.h - it has been closely modelled
after the one found in the Linux libc.

There still exist problems with `-traditional' because of stringizing
issues, but we probably don't want to work around this.
