Good luck!  FreeType 2 is rather tightly bound to ANSI C...

Instead of your solution I suggest that you simply redefine
FT_IMAGE_TAG to return an integer:

  #define FT_IMAGE_TAG( a, b, c, d )  \
            ( (unsigned int)a << 8 | (unsigned int)b )

We can provide this

  #ifndef FT_IMAGE_TAG
  #define FT_IMAGE_TAG ...
  #endif

in ftimage.h so that you can put your redefinition into a
Atari-specific subdirectory (`builds/tos' or `builds/atari').

David, what do you think about abandoning FT_IMAGE_TAG altogether?
What was the original intention for it?  A simple enumeration (as
pointed out by Wolfgang) should also work.

Wolfgang, may I ask that you contribute your changes after finishing
the port?
