Build Curl
========================================================
    1. Pre Build
  
    a. create bat file for debug
    call "C:\Program Files\Microsoft Visual Studio\VC98\Bin\vcvars32.bat"
    set CFG=debug-dll-ssl-dll-zlib-dll
    set OPENSSL_PATH=D:\svn_work\MDS\USS\trunk\openssl-0.9.8g
    set ZLIB_PATH=D:\svn_work\MDS\USS\trunk\zlib123-dll
    nmake -f Makefile.vc6

    b. create bat file for release
    call "C:\Program Files\Microsoft Visual Studio\VC98\Bin\vcvars32.bat"
    set CFG=release-dll-ssl-dll-zlib-dll
    set OPENSSL_PATH=D:\svn_work\MDS\USS\trunk\openssl-0.9.8g
    set ZLIB_PATH=D:\svn_work\MDS\USS\trunk\zlib123
    nmake -f Makefile.vc6

    c. save shell code to bat file
    Save to : curl-***\lib\build.bat

    d. modify curl-***\lib\Makefile.vc6
    Find
        CFLAGS     = /I. /I../include /nologo /W3 /GX /DWIN32 /YX /FD /c /DBUILDING_LIBCURL
    set as
        CFLAGS     = /I. /I../include /nologo /W3 /GX /DWIN32 /YX /FD /c /DBUILDING_LIBCURL  /I"C:\Program Files\Microsoft Platform SDK\Include"

    e. copy zlib123\projects\visualc6\Win32_DLL_Release\zlib1.lib to curl-7.18.1\lib\zdll.lib

    2. Build
