委托模板元编程的问题

下面的代码是由另一个程序员从Yingle Jia的代码中改编的，我必须将其移植到Linux上。它在VS2010中编译得很好，但是当我尝试用gcc 4.6.3在Ubuntu中构建时，它在

template <class R ACF_DELEGATE_COMMA ACF_DELEGATE_TEMPLATE_PARAMS>
class  Delegate<R (ACF_DELEGATE_TEMPLATE_ARGS)>

错误信息为:

../../../mySDK-master/include/abc/DelegateTemplate.h:45:1: error: pasting "," and "class" does not give a valid preprocessing token
../../../mySDK-master/include/abc/DelegateTemplate.h:46:1: error: pasting "," and "T" does not give a valid preprocessing token
../../../mySDK-master/include/abc/DelegateTemplate.h:74:1: error: pasting "," and "a" does not give a valid preprocessing token

第45行和第46行是我粘贴在上面的DelegateTemplate.h的两行代码。

是因为在gcc中缺乏模板元编程支持吗?我检查了是否因为可变模板，但这应该在gcc 4.3中修复。如果您能帮忙解决这个错误，我将不胜感激。
