[ns] gcc/g++ compiling problem

[=?gb2312?q?=CF=E6=BA=CD?=]

Hi, everybody:
   
  I program using STL. there is a member function of templete class map, I use the fucntion well with visual studio 2003 .net, but when I compile those code under cygwin, the compiler says this fucntion is wrong, why?
  I code my program with standard C++.
   
  In the book <<C++ prime plus>>, the writer says he have test his code, in the book, under vstudio 2003 and linux with gcc version 3.3.1.
   
  my gcc version for cygwin is 3.3.1. Then I install a new version 4.0.1, it gives the same error information.
   
  Regards
  Yang
