[Bug c++/15595] New: wierd compilation error

["eranti at aol dot net" <gcc-bugzilla at gcc dot gnu dot org>]

sample program

#include <string>
class strlessss {
   public:
       bool operator  () (int _X, int _Y) const
               {
                           return (_X < _Y);
                               }
};

Eranti1 (12:41 PM): and tried to compile it
Eranti1 (12:42 PM): this is the error i get
Eranti1 (12:42 PM): nibster:/tmp/ =) g++  -c -
I/h/nibster.nscp.aoltw.net/export/home/vijay/sam/thirdparty/boost/include/ t.cpp
t.cpp:4: error: parse error before numeric constant
t.cpp: In member function `bool strlessss::operator()(...) const':
t.cpp:6: error: `_Y' undeclared (first use this function)
t.cpp:6: error: (Each undeclared identifier is reported only once for each
  function it appears in.)

Eranti1 (12:42 PM): when i see preprocessor output with -E option, i am amazed
Eranti1 (12:42 PM): # 
58 "/export/home/vijay/gcc33/usr/local/include/c++/3.3.2/string" 2 3
# 2 "t.cpp" 2
class strlessss {
   public:
       bool operator () (int 0x00000080, int _Y) const
               {
                           return (0x00000080 < _Y);
                               }
};

Eranti1 (12:42 PM): so, string.h is defining _X to numeric constant

i am using 3.3.2 gcc which is fairly new. I am going to change all references 
to _X to _XX
