[Lemon-devel] Testing request

[Alpár Jüttner]

Very strange. Gcc does not compile LEMON  with this patch, and I think
gcc it right here for there are two contradicting declarations now. Two
ideas that we can try:
      * Declare the class first, then define the function wrappers
        immediately. In this way we can avoid the multiple occurrences
        of these functions
      * Declare/define one more overload instead of using default
        values.

Best regards,
Alpar
