[Zlib-devel] Fwd: zlib will not compile successfully under Windows 7, VC++2010 with Windows SDK7.1 in 64bit - discussion

[Mark Adler]

Any VC++2010 folk,

Below is an email about problems with compiling zlib.  Interestingly, nother VS2010 fellow had only the io.h problem.  In any case, if someone can provide some insight here, I would appreciate it.  Thanks.

Mark
