减小vc编译程序的体积

 不算原创，算是实践吧

网上搜了些资料，照做效果不是很好，

就把几种做法综合尝试一下，算达到了自己比较满意的效果

1. release版，（废话），程序还有24k

2. Project Setting ->Linker勾上 Ignore all default libraries，加上所需的库（msvcrt.lib，等），减到16k

3. 加了#pragramm comment(linker, "/opt:nowin98"),减到5k

4. 再加上区段合并，减到4k

没试再加壳，自己基本满意了

附一个头文件，直接引用，编译出的程序减到3k，强人真多啊

 #ifdef NDEBUG

#pragma optimize("gsy",on)

#pragma comment(linker,"RELEASE")

#ifdef _MERGE_RDATA_

#pragma comment(linker,"/merge:.rdata=.data")

#endif

#pragma comment(linker,"/merge:.text=.data")

#pragma comment(linker,"/merge:.reloc=.data")

#if _MSC_VER >= 1000

#endif

#endif

#pragma comment(linker,"/ENTRY:WinMain")

#pragma comment(linker,"/merge:.rdata=.data")

#pragma comment(linker,"/merge:.text=.data")

#pragma comment(lib,"msvcrt.lib")

#if (_MSC_VER < 1300)

#pragma comment(linker,"/IGNORE:4078")

#pragma comment(linker,"/OPT:NOWIN98")

#endif

#define WIN32_LEAN_AND_MEAN
