This isn't my day...

FileParser.tab.c: In function `int Fileparse()':
FileParser.tab.c:2043: error: syntax error before `goto'

The offending lines bison generated are:

/*----------------------------------------------------.
| yyerrlab1 -- error raised explicitly by an action.  |
`----------------------------------------------------*/
yyerrlab1:

  /* Suppress GCC warning that yyerrlab1 is unused when no action
     invokes YYERROR.  */
#if defined (__GNUC_MINOR__) && 2093 <= (__GNUC__ * 1000 + __GNUC_MINOR__)
  __attribute__ ((__unused__))
#endif

  goto yyerrlab2;     <== line 2043

I'm using bison 1.875.  But it worked the last time, so I don't know why
it doesn't work now.  Deleting the __attribute__ clause fixes it.
