Re: [ft-devel] freetype 2.3.8 warnings

Dear Werner,

As soon as I update Xcode in my Macintosh, I will check
this issue. I'm sorry for I could not help previous
autogen.sh issue on Mac OS X.

Me too, at present.

I guess it can be related with LP64 issue. In my LP64 patch,
there was a modification of fttrigon.c aslike:

@@ -433,7 +433,7 @@
 
       if ( shift > 0 )
       {
-        FT_Int32  half = 1L << ( shift - 1 );
+        FT_Int32  half = (FT_Int32)1L << ( shift - 1 );
 
 
         vec->x = ( v.x + half + FT_SIGN_LONG( v.x ) ) >> shift; /* WARNED */
         vec->y = ( v.y + half + FT_SIGN_LONG( v.y ) ) >> shift; /* WARNED */
