[Zlib-devel] Wanring on 64 bit compiler

[Gilles Vollant]

When I compile zLib 1.2.1 with Microsoft 64 bits compiler, I had 2 warning.

Here is the warning, the original line and my modification
 
inftrees.c(257) : warning C4334: '<<' : result of 32-bit shift implicitly
converted to 64 bits (was 64-bit shift intended?)
            next += 1U << curr;
            next += ((size_t)1U) << curr;

inflate.c(1266) : warning C4334: '<<' : result of 32-bit shift implicitly
converted to 64 bits (was 64-bit shift intended?)
        zmemcpy(window, state->window, 1U << state->wbits);
        zmemcpy(window, state->window, ((size_t)1U) << state->wbits);
