1342: - Watcom C pretends to be Microsoft C small model even in 32 bit mode.
1343: - don't use unsized arrays to avoid silly warnings by Visual C++:

1354: (it's now sufficient to set MAX_WBITS in zconf.h).
1355: - voidp -> voidpf and voidnp -> voidp (for consistency with other
1356: typedefs and because voidnp was not near in large model).
