__GNUC__ == "mingw" in w32.c

[Juanma Barranquero]

>From w32.c:

  #ifdef _MSC_VER
  #define COMPILER_NAME   "msvc"
  #else
  #ifdef __GNUC__
  #define COMPILER_NAME   "mingw"
  #else
  #define COMPILER_NAME   "unknown"
  #endif
  #endif

Is there any reason to consider any _GNUC_ compiler as "mingw"?
Wouldn't be more sensible to use

  #ifdef _MSC_VER
  #define COMPILER_NAME "msvc"
  #else
  #ifdef __MINGW32__
  #define COMPILER_NAME "mingw"
  #else
  #ifdef __GNUC__
  #define COMPILER_NAME "gcc"
  #else
  #define COMPILER_NAME "unknown"
  #endif
  #endif
  #endif

or some such?
