 Dears,

 There is little problem with ASIO on windows.
 ASIO is using windows.h header.
 That header defines "min" and "max" macros.

 So immediately asio is conflicting with standard
 <limits> and <algorithm> headers.

 The error generated by the compilers is higlhy not readable.
 Also regular user of the asio does not know that windows.h
 is included and pollute standard C++ code with mentioned
 macros.

 Try to use
 ::std::numeric_limits<int>::min()
 ::std::numeric_limits<int>::max()
 as well as
 ::std::min()
 together with ASIO.

 For users would be perfect if you
 could simply put
 #undef min
 and
 #undef max
 just after inclusion of any windows.h
 file.

 The problem is more complicated because the
 same code is working on Linux,
 so from C++ portable code it is uncomfortable
 to have such a intrusions.

 Best regards,
 Seweryn Habdank-Wojewodzki
