mingw-freetype (rjones, lfarkas, epienbro)

This uses:

%{!?_with_subpixel_rendering: %{!?_without_subpixel_rendering: %define _without_subpixel_rendering --without-subpixel_rendering}}

_without_subpixel_rendering is not used anywhere else in the file.
No idea if that is right or not.

Another case where %define is actually wrong. The whole construct
looks like a workaround for %bcond related misunderstanding, but
dunno.

Actually in this second case, mingw-freetype.spec is just following
the freetype.spec file.  Which also looks wrong because it defines
_without_subpixel_rendering which is never used anywhere.

Right. Freetype is old enough to actually predate rpm's %bcond_with/without so custom variants have been implemented + evolved by various packagers over the years, but this should've really been using %bcond already:
http://pkgs.fedoraproject.org/cgit/rpms/freetype.git/commit/freetype.spec?id=417715cf8e484f8099e6c2561e1ba83e851d9751

This is what it should be changed to (untested but should be "obviously correct"):
