c语言新手 c++模板问题

//----------------queue.h------------------------

export  template<class Type>
class queue {
    //...
};

//---------------queue.c-------------------------
#include "queue.h"
....

gcc queue.c -c -o queue.o

提示:queue.h:1: warning: keyword `export' not implemented, and will be ignored
难道gcc不支持导出模板

而且我按照书上的试验模板分离模式编译通不过,这是怎么回事,望高手指点.

Missing features

The export keyword is not implemented.

    Most C++ compilers (G++ included) do not yet implement export, which is necessary for separate compilation of template declarations and definitions. Without export, a template definition must be in scope to be used. The obvious workaround is simply to place all definitions in the header itself. Alternatively, the compilation unit containing template definitions may be included from the header.

现在没几个编译器支持export关键字。
