[Mingw-w64-public] Detect difference at compile time between mingw and mingw-w64

[Luis L. <lui...@gm...>]

Hello Guys,

I'm trying to find any document or hint on how to detect the different
vendors without checking the triplet of GCC.

Is there a define I can use to compare?

I know __MINGW32__ is defined on both mingw.org and mingw-w64 and
*also* defined when compiling with mingw-w64 in 64bits mode.

Thank you in advance and apologies if this was already answered, by
keyword search didn't return any useful information.
