Please, people, DON'T followup to this.  This subject was hashed
to death in comp.lang.c.  The construct cited in the article
" if (ptr) { do something }". is both valid and 100% portable, at least
according to both Kernigan and Richie, and the proposed ANSI standard.
Perhaps Martin has a buggy compiler that will not accept this construct,
but all correct C compilers handle it as written.
