48 | * The __CONCAT macro is used to concatenate parts of symbol names, e.g. |
49 | * with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo. | |
50 | * The __CONCAT macro is a bit tricky -- make sure you don't put spaces | |
51 | * in between its arguments. __CONCAT can also concatenate double-quoted | |
52 | * strings produced by the __STRING macro, but this only works with ANSI C. | |
