/*
* The __CONCAT macro is used to concatenate parts of symbol names, e.g.
* with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
* The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
* mode -- there must be no spaces between its arguments, and for nested
* __CONCAT's, all the __CONCAT's must be at the left. __CONCAT can also
* concatenate double-quoted strings produced by the __STRING macro, but
* this only works with ANSI C.
*
* __XSTRING is like __STRING, but it expands any macros in its argument
* first. It is only available with ANSI C.
