Unless I am missing something, there may be some problems with this.
The first thing that needs to be done is pasting prefix and suffix to allow
handling something like "unsigned int":
PREFIX_unsigned int_SUFFIX
However doing the same with, say, "enum(color)" would have to produce:
PREFIX_enum(color)_SUFFIX,
And I am pretty sure some preprocessors (for example GCC) would have a
problem with pasting anything to ')'.
But maybe you have something else in mind?
