|BISON reentrance bug firstname.lastname@example.org (Brian Robertson) (1995-05-10)|

I am trying to get a re-entrant %pure parser working with BISON.
It calls itself fine, parses and returns, but there is a look-ahead
token left over from the recursive parse, which causes the parse to fail.
I have tried the 'yyclearin' call, after the recursive call to yyparse
returns but that did not help. It has gone one token too far and it needs
to backup and re-read the exact same token.
Any ideas on how to solve this problem would be very helpful!
