[freetype2] master 3f6497bdc: Add Watcom C/C++ calling.

[Werner Lemberg]

branch: master
commit 3f6497bdc53bf19c1ac07cfbb121d7c51966b0d7
Author: Ozkan Sezer <sezeroz@gmail.com>
Commit: Alexei Podtelezhnikov <apodtele@gmail.com>

    Add Watcom C/C++ calling.
    
    In the unlikely case the source is built with OpenWatcom's -ec?
    switches to enforce a calling convention, the qsort() compare
    function must still be set to __watcall.
    
    * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF):
    Updated.
