[Devel] standalone ftgrays.c

[Scott Long]

I tried following the directions in ftgrays.c (lib version 2.1.2) to 
compile a standalone antialiasing rasterizer. After copying the 
necessary files, I try to compile:

$ gcc -D_STANDALONE_ -c ftgrays.c
In file included from ftimage.h:31,
                 from ftgrays.c:117:
/usr/include/ft2build.h:55:38: freetype/config/ftheader.h: No such 
file or directory

No problem, so I add the include path to the Freetype headers, and 
after compiling again I get this error:

ftgrays.c: In function `gray_render_span':
ftgrays.c:1287: `FT_UInt' undeclared (first use in this function)
ftgrays.c:1287: (Each undeclared identifier is reported only once
ftgrays.c:1287: for each function it appears in.)

As a quick fix without even changing the source, I try:

$ gcc -D_STANDALONE_ -c -DFT_UInt='unsigned int' 
-I../freetype2/include ftgrays.c

And that succeeds.

I just want to report that this does work, but not in the way 
documented in ftgrays.c. Does my workaround actually work? Or am I 
missing something important here? Regardless, it appears that the 
hints given in ftgrays.c are either incorrect or out of date.
