Detailed Description

History

• 2009/08/25 Shinigami: STLport-5.2.1 fix: additional parentheses in asserteql
• 2010/03/27 Shinigami: Notes added.

Note

How does it work?
asserteql
defines one "char xxxyyyzzz[1];" globaly. per check it tries to define another "char xxxyyyzzz[1-(0)];" (a^(b) = a XOR b). if this is not possible, than it will fail, due to different definitions.
assertsize
tries to define two entries in a different way. if this is not possible, than it will fail, due to different definitions.
assertofs
will not be used.
Why we have asserteql and assertsize if it does the same? dunno

ATTENTION This header is part of the PCH Remove the include in all StdAfx.h files or live with the consequences :)
