Hi avati,

   Please find the attached patch. Well now the configure will exit for
byacc parser as it doesn't have yylval defined as YYSTYPE inside
y.tab.h of which bison has

I tried adding a below type of code to spec.y to actually support byacc.
But  found some errors further.

#if ! defined YYSTYPE && ....
typedef int YYSTYPE;
extern YYSTYPE yylval;

Which byacc lacks yylval declaration inside y.tab.h. Sole reason why build
breaks. Right now byacc will not be supported as parser for glusterfs.
