实际上，我正在比较编程语言之间的数据类型，这是我在阅读C和C++标准时遇到的问题。引用自C11，wctrans_tisascalartypethatcanholdvalueswhichrepresentlocale-specificcharactermappingswctype_tisascalartypethatcanholdvalueswhichrepresentlocale-specificcharacterclassifications短语ascalartype表示C11不限制wctrans_t和wctype_t为特定标量类型。我的MinGWGCC4.8实现了wctrans_t

在OSX10.9.1上使用g++从命令行编译基本代码(我附加了一个helloworld作为示例)时#includeintmain(){std::cout我用命令编译:g++hello.cc-ohw这会生成以下错误消息:Infileincludedfromhello.cc:1:Infileincludedfrom/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/iostream:38:Infileincludedfrom/Applicat
