warning C4130: '==' : logical operation on address of string constant

环境：vs2010，c++

#define UNIT_FONTSIZE _T("rem")
if(UNIT_FONTSIZE == _T("rem"))
{
//...
}

代码有警告：

warning C4130: '==' : logical operation on address of string constant

修改：

使用_tcscmp代替==进行判断

if(_tcscmp(UNIT_FONTSIZE, _T("rem")) == 0)
{
//...
}
