Another g-wrap bug (with patch): enumerations create symbol conflicts

[Derek Atkins]

Rob,

I tracked down another g-wrap bug.  In this particular case the
enumeration C-code generator would create mutliple files that defined
the same (exported) variable.  This caused problems, specifically when
linking two g-wrap-generated C files together (either into the same
library or app or other non-lazy linking scenario) when both files
reference the same enum.

The fix is simple: turn the gw__enum__<type>_val_to_int_scm_func and
gw__enum__<type>_int_to_val_scm_func variables into 'static's.

The following patch makes this change, and I've tested it on my
gnucash build with sucess.

Thanks!
