I'd think the error message is pretty clear. You have a prototype
declaration of RegExec in line 70 of RegExp.hpp that defines default
arguments.

You have another prototype declaration (or a definition) in line 74,
and this provides default arguments as well. It is an error to give
default arguments twice in standard C++.

Hope this helps,
Martin

(and yes, the source code of the respective lines in question would
have helped)
