Compilers Supported
-------------------
MinGW GCC (recommended)
MSVC 6.0 SP6: You'll need Boost version 1.34 because they dropped support
for MSVC 6.0 after that. However, they didn't add Asio until 1.35.
You should still be able to build with MSVC 6.0 by adding Asio to 1.34 by
unpacking boost_asio_*.zip into the boost directory:
http://sourceforge.net/projects/asio/files/asio
http://tdm-gcc.tdragon.net/ has an easy installer. Go back a few versions
for a little older gcc like gcc 4.4.?.
MSVC 8.0 (2005) SP1 has been tested. Note: MSVC 7.0 and up have a habit of
linking to runtime DLLs that are not installed on XP by default.
