pdf2swf transcodes fonts. It takes the fonts polygons and uses them to 
create a FlashType font. As pdf2swf only uses the polygons in a font,
and nothing else, hinting doesn't make any difference- it would only 
affect how freetype would create bitmaps from the font, but not the
polygon outlines.
Hence, we don't need hinting, and leaving it turned on actually did
cause problems with fonts that had incorrect hinting information or 
broken bytecode.

So the only difference your patch might make is when you convert files
using "-s bitmap", as that is the only way to have freetype-rendered
bitmaps in the SWF output.
If that was indeed your goal, then I believe it should be possible to
enable hinting based on the value of the "config_full_bitmap_optimizing"
setting.
