Hello,
If I to the following Bison grammar:
--------------------------------------------------------
%{
void dummy();
%}
%pure-parser
%%
Root: /* empty*/
{
}
%%
--------------------------------------------------------
adds %glr-parser under %pure-parser, two things happens beyond changing the
parser algorithm:
* It copies all the code in the c++ section into the header.
* It puts "extern YYSTYPE lval;" in the header.
None of these two things I like nor would expect(at least, to not be different
from a lr parser).
Why does these things happen when I add %glr-parser? How do I avoid it from
happening?
This was produced with Bison 2.3, by invoking bison --defines=t.h t.ypp.
Thanks in advance,
Frans
