[Devel] freetype2 FT_FREETYPE_H macro bug

[Tim Seufert]

Freetype2 defines FT_FREETYPE_H as follows:

#define FT_FREETYPE_H  <freetype/freetype.h>

On systems which have both freetype and freetype2 installed, if the 
header search path contains the *parent* dir of the freetype header dir 
*before* it lists the freetype2 header dir, this will lead to inclusion 
of the freetype1 freetype.h file.

What a mouthful.  Hopefully this will be more clear:

test.cpp:
#include <ft2build.h>
#include FT_FREETYPE_H
#include FT_CACHE_H
(etc.)

g++ -I/sw/include -I/sw/include/freetype2 -c test.cpp

result: massive b0rkenness because FT_FREETYPE_H ends up grabbing 
/sw/include/freetype/freetype.h instead of 
/sw/include/freetype2/freetype/freetype.h.

Yes, this really happened to me, while I was trying to port a package 
to Fink on MacOS X (thus the /sw/include dir instead of 
/usr/local/include, but I don't see why it wouldn't affect 
/usr/local/include too).

Please cc me with any responses as I'm not subscribed to the ft2 devel 
list.
