bison & flex - pure parser

[Giancarlo Luxardo]

In order to generate a reentrant scanner with flex, one must use %option
c++. With bison, %pure_parser allows to generate a reentrant parser.

Question: is it possible to use both tools together to link a reentrant
parser with a reentrant scanner? The two manuals do not provide details
about that. 

Any suggestion would be appreciated... It would be useful if someone has
made available some example...
