1341: - guard against multiple inclusion of *.h (for precompiled header on Mac)
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++:
1344: warning C4746: 'inflate_mask' : unsized array treated as '__far'

1353: - default window size is same for compression and decompression
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).
