[HarfBuzz] enum issue

Sat Mar 1 08:38:06 PST 2014

Compiling with -ansi using

  i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1
  (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

I get the following warning:

  hb-common.h:280: warning:
    ISO C restricts enumerator values to range of 'int'

Nothing really serious, but probably worthwhile to mention...
