As far as I know, rootcint can not be used with preprocessor because
1) ROOT header files uses special macro and comments which are essential to
sharedlib integration. Using the preprocessor strips those important
information.
2) As you observed with Soraris2.6, some preprocessor generates unexpected
lines in the output file.

This does not help. The situation is the same.
Will you inform the development team why you need to use preprocessor?
What expression do you need preprocessing? We might be able to suggest
something then.
