Hi Guido,

Thanks for committing the fix. There is one more, minor issue. I get a few
warnings when using Gecode headers with a high warning level:

  gecode/set.hh:1278: warning: comma at end of enumerator list
  gecode/float.hh:1653: warning: comma at end of enumerator list

Trailing commas in enums were only added in C++11 and, although most C++
compilers support them as an extension, I think it would be nice if headers
didn't rely on extensions. The attached patch fixes the warnings.

Cheers,
Victor
