| // 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. |
