 Hi,
 
 I'm working on Linux. The StdAfx.h comes from porting the software...
 
 The real problem was another:
 
 We have a declaration of min() and max() macros in our standard include
 (saptype.h).
 Unfortunately some C++ standard classes have a min() method. With the
 min() macro this is changed in an uncorrect way.
 
 Declaration of min() macro:
 #define min(a,b)       (((a) <= (b)) ? (a) : (b))
 
 From
 /opt/gcc-20010716/include/g++-v3/ia64-unknown-linux/bits/std_limits.h:
     ...
     template<typename _Tp> struct numeric_limits {
         static const bool is_specialized = false;
 
         static _Tp min() throw() { return static_cast<_Tp>(0); }
     ...
 This is preprocessed to something like
     ...
     template<typename _Tp> struct numeric_limits {
         static const bool is_specialized = false;
 
         static _Tp min throw() { return static_cast<_Tp>(0); }
     ...
 which of course is not correct.
 
 I mentioned it in another bug report for cpp, but this was closed as
 normal behaviour.
 The SUN compiler can distinguish in this case though.
 
 Best regards,
 Thomas

    You have not included any source code; we have no way of
    reproducing the bug.  You need to read the bug reporting
    instructions at http://gcc.gnu.org/bugs.html .  Please do
    so, and then send another bug report as a followup to this
    one (PR 3658).
    
    Also, the mention of "StdAfx.h" in your error message makes
    me think that you are working under Windows.  If this is
    the case, then you should be using the Cygwin tools.
