Description Alexander Larsson 2003-06-04 06:07:50 EDT
Building pwlib with bison-1.875-2 fails, because it uses the bison parser with g++.
The following code in yacc.c fails:

| yyerrlab1 -- error raised explicitly by an action.  |

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

]b4_location_if([  yylerrsp = yylsp;
  *++yylerrsp = yyloc;])[
  goto yyerrlab2;

since __attribute__ ((__unused__)) doesn't work in C++. I propose adding
!defined (_CPLUSPLUS_) or something.
Comment 1 Alexander Larsson 2003-06-04 06:08:48 EDT
(the attribute doesn't work for labels i mean)
Comment 2 Alexander Larsson 2003-06-04 06:13:50 EDT
(And i meant __cplusplus__ obviously)
