Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code. Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).
* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.
* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
requested.
* include/freetype/config/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.
* src/base/ftbase.h: Remove DARWIN_NO_CARBON.
* src/base/ftbase.c: Ditto.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Ditto.
* src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
(same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
* builds/mac/ftmac.c: Ditto.
* builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
* builds/mac/FreeType.m68k_far.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
The native SDK on earliest Mac OS X (10.0-10.1) did not have
"AvailabilityMacros.h". To prevent the inclusion of missing
header file, ECANCELED (introduced in 10.2) in POSIX header
file <errno.h> is checked to detect the system version.
* include/freetype/config/ftconfig.h: Conditionalize the
inclusion of "AvailabilityMacros.h".
* builds/unix/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.
builds/unix/ftsystem.c prevents to open an useless stream from
zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
stream drivers for ANSI C, Amiga and VMS return useless streams.
For cross-platform consistency, all stream drivers should act
same.
* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
file is zero, FT_Err_Cannot_Open_Stream is returned.
* builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
* src/vms/ftsystem.c (FT_Stream_Open): Ditto.
(some platforms don't provide this ANSI function !!)
some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!
