problem compiling Gtk2-1.060 from CPAN in xs/GdkKeys.xs + fix

[Sergey Bratus <sergey bear cs dartmouth edu>]

  Sorry if this problem has already been resolved. It was 
a bit of a surprise for me, and I apologize if this is well-known.

I encountered the error message below while buidling Gtk2-1.060
downloaded from CPAN today. The same error occurred on two different
systems with an older version of gcc (gcc 2.96 20000731) and
perl 5.8.0 .

It was apparently caused by the trailing ; in xs/GdkKeys.xs line 27:

#define SvGdkKeymap_orclass(sv) ((sv && SvOK (sv) && SvROK (sv)) ? 
SvGdkKeymap (sv) : NULL);
                        ^

Expanded, it resulted in double ;; in four locations in xs/GdkKeys.c,
causing syntax errors with gcc. 

Removing the training l from the above line allowed me to finish
building package without further problems.

Hope this helps someone,
