[freetype2] logging 4d68336 05/12: [dlg] Fix compiler warnings.

[Werner LEMBERG]

branch: logging
commit 4d683362840aa277e00f5905c4a20e306c803710
Author: Werner Lemberg <wl@gnu.org>
Commit: Werner Lemberg <wl@gnu.org>

    [dlg] Fix compiler warnings.
    
    * src/dlg/dlgwrap.c: Duplicate some feature test macros from
    `dlg.c`, which must come first before loading standard headers.  For
    example, `freetype.h` loads `stdio.h` if compiled in debug mode.
