+//  Boost.System calls operating system API functions to implement system error category
+//  functions. Usually there is no question as to which API is to be used.
+//
+//  In the case of MinGW or Cygwin/MinGW, however, both POSIX and Windows API's are
+//  available. Chaos ensues if other code thinks one is in use when Boost.System was
+//  actually built with the other. This header centralizes the API choice and prevents
+//  user definition of API macros, thus elminating the possibility of mismatches and the
+//  need to test configurations with little or no practical value.
