The header files didn't change because the "fix" was to install the
header files as follows:

   $(prefix)/include/freetype2/
                       freetype/
                          config/
                          cache/
                          internals/
                          freetype.h
                          ....

The only "down-side" is that applications need to be compiled with
a specific include path, like -I/usr/local/include/freetype2.
(non-Unix platforms already require this)

Note that "make install" now installs a script named "freetype-config" that
can be used by other configure scripts to detect where FreeType 2 is installed
and what compiler or linker flags to use when an application uses the
library.. with commands like:

  "freetype-config --cflags"  => returns C flags to use, e.g.  
"-I$(prefix)/freetype2"
  "freetype-config --libs"    => returns linker flags, e.g.    "-L$(prefix)/lib 
-lfreetype"

Note that I didn't write an ACLOCAL macro though, but I hope some Autoconf
expert out there will be able to do that soon.. Except than that, I believe
we're now pretty Unix-compliant !

Any comments ??
