I have added this useful construct to the lcc-win compiler.

Description:

#include <assert.h>
static_assert(boolean expression, message)

The boolean expression will be evaluated at compile time.

If the "boolean expression" is true at compile time, nothing happens,
the whole becomes a NOP (no operation).

If the boolean expression fails, the character string "message" will be
printed in an error message. The compiler appends the failed expression
to the message. The compilation fails and no object code is generated.

If the boolean expression can't be evaluated at compile time, the
compiler will generate a call to the _StaticAssert function, that will
print the error message at run time if the expression fails and exit the 
program.

What do you think?

Commentaries welcome.
