The following builds were still failing due to previous changes:
make multi
make multi CC="c++"
make CC="c++"
This patch fixes the issues, which were missing includes to get the
right macro definitions in multi-build mode.
Also, `FT_UNUSED' is actually used by third-party code, so move it
back to `public-macros.h' to avoid breaking it.
* include/freetype/config/public-macros.h (FT_EXPORT): Remove
special definition for C++.
(FT_UNUSED): Define here instead of...
* include/freetype/config/compiler-macros.h: ... here.
(FT_FUNCTION_DECLARATION): Remove special definition for C++.
(FT_LOCAL_ARRAY_DEF): Fix definition.
* src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,
src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.
* include/freetype/config/public-macros.h
(FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as
public (and thus exportable).
(FT_EXPORT): Use it.
* include/freetype/config/compiler-macros.h
(FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as
internal to the library (and thus hidden). Note that on ELF
systems, all internal functions have hidden visibility, which avoids
the need to enforce this when invoking the compiler (e.g., with an
option like `-fvisibility=hidden').
(FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros
to deal with C and C++ linkage issues at the same time.
(FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF,
FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK,
FT_BASE_CALLBACK_DEF): Redefined using new macros.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions
required by the FreeType API headers to...
* include/freetype/config/public-macros.h: ...this new file.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions used
by the library but not to be exposed to clients to...
* include/freetype/config/compiler-macros.h: ...this new file.
* include/freetype/internal/*.h, src/raster/ftraster.h: Include
`compiler-macros.h' where needed.
