I didn't look how you formatted it, but note that in C++ (which I
realize freetype is not written in) gcc 4.2 will warn for code like this:

for (i = 0; i < 10; i++);

But it will not warn if you do:

for (i = 0; i < 10; i++) ;


for (i = 0; i < 10; i++) {}

Oddly, the warning only applies to C++ and not C.

Just something to consider...
