You can do this, at least in GCC 4.0.2:
#define stdio <stdio.h>
...
#include stdio
Ugly. The FreeType library uses this feature/hack to get the right
include files included, which is the only reason I discovered that it
was possible. You do this sort of thing:
#include <ft2build.h>
#include FT_FREETYPE_H
#include FT_GLYPH_H
#include FT_OUTLINE_H
#include FT_BBOX_H
I don't think I ever found out why you'd want to do it that way, but
there you are.

Nice. So you could do tasteful things like this, at least if they
were allowed at the start of an identifier:
int sum (int *@numbers, int $size)
{
int $total = 0;
int $i;
for ($i = 0; $i < $size; ++$i) {
$total += @numbers[$i];
}
return $total;
}

C++ was stillborn.
