This probably is mentioned somewhere on the wiki, but heck, here goes:
The "x86_64-w64-mingw32" and "i686-w64-mingw32" are target triplets:
- The first part is the archtecture: x86_64 (64-bit) and i686 (32-bit)
- w64 is the "vendor" part, usually it's pc, unknown, gnu, etc...
- mingw32 is the OS part. The 32 is somewhat confusing, but derived from
Win32, the API that all desktop Windows versions adhere to and use. It has
nothing to do with architecture.
There were movements to rename mingw32 to mingw, but that never happened
for some strange unknown-to-the-world reason.
MinGW.org (the "mingw32" as you and pretty much the rest of the
cross-compiling world call it) misused its "monopoly" before MinGW-w64 and
was lazy, reducing the triplet to a single string: mingw32, or if they were
a bit nicer, i?86-mingw32.
Hope this clears up the confusion.
