The FT_INT64 stuff is only used in a single file, `src/base/ftcalc.c'.
However, AFAIK, the GNU C compiler always defines a 64bit data type
(`long long int'), so I'm really surprised that you experience this
problem.  Perhaps this is different for GNU C on ARM?

Can you try

  make devel
  make

(from a fresh tarball) for compiling FreeType so that you bypass the
`configure' script?  Do you then get correct results for your demo
application?

Can you please also post the file `builds/unix/config.log'
(compressed)?

Finally, can you decorate the various functions of ftcalc.c with some
printf calls to find out where the difference comes from?  Up to now,
we've never received a similar problem report.
