Sorry for long long long lated issue.

Now, src/base/ftbase.c includes ftmac.c by

        #include <ftmac.c>

syntax. The inclusion by <> does not search the current
directory implicitly, so it requires appropriate CFLAGS
pointing the directory that has ftmac.c. I designed
builds/unix/configure.raw to set appropriate CFLAGS with
consideration of configure options (e.g. force to use
legacy QuickDraw API). In fact, before I inserted such
hook, builds/unix/configure.raw included the current
directory (e.g. freetype-x.y.z/src/base) explicitly.

There are some softwares that merges freetype2 source
codes into their own souce code tree, and sets CFLAGS by
their own mechanism, without configure.raw in freetype.

For such softwares, the simple inclusion by "" is easier
because it searches the current directory implicitly.
It is why Sean McBride asked to replace

        #include <ftmac.c>

        #include "ftmac.c"

The most generic advice for such softwares is "please
add -I${freetype_top_dir}/src/base to CFLAGS". In my
personal opinion, if a software designer does not use
genuine freetype configure/Jamfile/project file, he is
responsible to the setting of appropriate CFLAGS.

But I'm afraid there are too many unactively-maintained
softwares including freetype to tell that. So rewriting
ftbase.c for easy dropin-update is not meaningless, I
think. Following patch is too ugly for ftbase.c?

Other idea may be: use a macro FT_MAC_C to include non-
default (legacy) ftmac.c and expects builds/unix/configure.raw
to define it. If it's not defined, include default
(Mac OS X-only) src/base/ftmac.c.
