i#118517# - Update twain to version 2.1 with support for Apple and UNIX. 

Mingw apparently tries to pass as GNUC and WIN32/64 so we detect it early and force it to work like in previous versions.

Cherry-picked from:

e1431bbb

Also contains:

f3011056 - Fix issue with twain header.
1d6adce0 - Minor style fix.
