-------------------------------+--------------------------------------------
 On a mingw32 build of libs/asio/example/http/async_client.cpp using gcc
 4.5, an access violation is created when the HTTP client is pointed to an
 address which refuses the connection. When adding a
 `LoadLibrary("exchndl.dll");` (stack dump tool from mingw-utils), I get
 the following stack trace:

 Z:\tmp\a.exe caused an Access Violation at location 004277d1 in module
 Z:\tmp\a.exe Reading from location 00000200.

 Registers:

 When compiling with -DBOOST_ASIO_DISABLE_THREADS, I get the following
 error message instead:

 Exception: thread: Unknown error
