Hi,

Maybe your version of bison doesn't support the -p option?

In libglusterfs the
    bison -y -p graphyy  ./graph.y

should have produced a y.tab.c file with

...
#define yylex           graphyylex
...
int graphyylex ();
...
       yychar = yylex ();
...

Which is what we get on Linux, MacOS, and *BSD.

That's a reasonable work-around/hack. At least your flex seems to 
support the -P option correctly.

Those seem reasonable. Fedora21 has flex 2.5.37 and boson-3.0.2

That would be great. Thanks.
