Loops in GCC preprocessor needed

[Jonathan Wakely]

The behaviour of the C preprocessor is defined by the ISO C standard,
not by GCC. It is not likely that GCC would add non-standard
extensions to add such features to the preprocessor.

You could look at
http://www.boost.org/doc/libs/1_60_0/libs/preprocessor/doc/ to see
what can be done using the standardpreprocessor, or you could look
into other ways to generate the code before you compile it.
