* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function
to support new pathname syntax "..namedfork/rsrc" to access
a resource fork on Mac OS X. The legacy syntax "/rsrc" does not
work on case-sensitive HFS+.
(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
buffer size to store a pathname.
* include/freetype/internal/ftrfork.h: Increment the number of
resource fork guessing rule.
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: improve the compile tests to search
