vs2008 编译zlib 1.2.3

vs2008 发现无法编译zlib 1.2.3。出错信息为：

inffas32.asm(594) : error A2070: invalid instruction operands
inffas32.asm(596) : error A2070: invalid instruction operands
inffas32.asm(610) : error A2070: invalid instruction operands
inffas32.asm(667) : error A2070: invalid instruction operands

原因在于

It (Microsoft Macro Assembler 8.0, included with Visual C++ 2005 Express ) refuses to assemble a MOVD instruction with a memory operand with an implied size, and requires that "dword ptr" prefix the memory operand.

微软说这是by design，不是bug：

解决办法是把inffas32.asm中的4处出错的类似

 movd mm4, [esp+0]

的汇编代码，添加dword ptr修饰符，改为

 movd mm4,dword ptr [esp+0]

这样就能顺利编译、通过测试了。
