Hi Antonio,

In lzlib (lzlib.h) you're using
extern const CRC32 crc32
which might (and for me will) collide with own applications that lzlib is linked with (since another variable or function named crc32 is quite common...). Especially this might lead to crashes when it is used as shared lib.

Can you please rename that variable to (for example) lz_crc32 if needed as extern at all?

[ For completeness the
extern const Dis_slots dis_slots;
extern const Prob_prices prob_prices;
might be prefixed with lz_ also? ]
