As noted in a sideband dialog, you are right, this would be wonderful, and can
be done with additional work to define z_off64_t in terms of __int64 for the
public zconf.h header on win32.  But since this is not done yet, and because
the existing stubs expected 32 bit arguments and not 64 bit arguments, these
exports were premature and would have introduced very hard-to-debug binary
incompatibility.

Now, it will be a simple binary condition, the symbols are resolved at runtime
or the binary will fail to load zlib1.dll due to missing symbols.  No nested
surprises.
