[DotGNU]error in make pnet

[Enrico Donelli]

Hello everybody,
i downloaded the pnet sources from CVS, but compiling pnet I get the 
following error:

make[1]: Entering directory `/home/enrico/download/pnet/pnet/ilasm'
byacc  -d ilasm_grammar.y && mv y.tab.c ilasm_grammar.c
byacc: e - line 872 of "ilasm_grammar.y", syntax error
%expect 8
^
make[1]: *** [ilasm_grammar.c] Error 1
make[1]: Leaving directory `/home/enrico/download/pnet/pnet/ilasm'
make: *** [all-recursive] Error 1


I already compiled and installed treecc.
(I use mandrake 8.2)

Any idea?

thanks in advance
Enrico
