[PATCH] Avoid pointer arithmetic on `void *'.

[Ralf Wildenhues]

* modules/m4.c (dump_symbol_CB): Cast obstack_base return value
to `char *' before using it.

Hi Eric,

found this while trying to build master on Tru64/OSF1, where the
compiler warns about void * arithmetic by default.

Cheers,
Ralf
