+//  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.

+    //    systems that return some POSIX errno values and some native errno
+    //    values. This code should not have to pay the cost of distinguishing

+    //
+    //  * Users wishing to write system-specific code should be given enums for
+    //    at least the common error cases.
+    //
+    //  * System specific code should fail at compile time if moved to another
+    //    operating system.
