编译pygame的wince版本

预先准备的包参见前一篇文章。（包括需要copy的目录和文件）

1. 下载并编译SDL 1.2.13

2. 对Pygame的代码进行修改：去掉signal.h,long long.（去掉Longlong会对transform有影响，不过暂时用不到，不知道有没有更好的解决方案）

3. 将编译wince需要的文件copy到pygame/ce下

4. 修改SConstruct文件如下：

class CEBuildEnvironment(Environment):
	def __init__(self):
	    Environment.__init__(self, 	 
	        MSEVC_PLATFORM = 'POCKET PC 2003',
	        MSEVC_SUBPLATFORM = 'Win32 (WCE ARMV4)',
	        tools = ['mslink', 'msevc', 'zip'],
	        toolpath = '.'
	        )

class PythonCEBuildEnvironment(CEBuildEnvironment):
	def __init__(self):
	    CEBuildEnvironment.__init__(self)
	    self.Append(CPPDEFINES = ['WIN32'],
	                LIBS=["python25","SDL"],
	                CPPPATH=["include","../../SDL-1.2.13/include"],
	                LIBPATH=["lib","../../SDL-1.2.13/VisualCE/SDL/Pocket PC 2003 (ARMV4)/Debug"])

	def PythonExtension(self, target, sources, **kw):
	    self.SharedLibrary(target, sources, SHLIBSUFFIX='.pyd', **kw)

lines = """

env = PythonCEBuildEnvironment()
for l in lines.splitlines():
    if l.startswith('#'): continue
    names = l.split(' ')
    fns = ['../' + x for x in names[1:-2]]
    env.PythonExtension("build/%s.pyd" % names[0], fns)

5. 执行scons.py

6. 将生成的pyd文件替换到windows版本的pygame中，然后去掉无用的.dll文件，将新的pygame复制到wince的python25/lib下，即可
