    It is probably related to the getline Template Function Reads Extra Character bug in MSVC++6. Applying the fix given in that page (which is re-expressed in "getline" bug fix for Microsoft Visual C++ 6.0) should solve the problem.

    While you're at it, mucking around with the system header files, might as well take care of the other "issues" with MSVC.

    Damn MSVC sure has issues
    Good class architecture is not like a Swiss Army Knife; it should be more like a well balanced throwing knife.
