Subject: [PATCH] Add a hack to allow an external jpeg library to still be used
 on cygwin/mingw/wine now that their windows headers define a type boolean
 conflicting with the jpeg headers.

+// This hack is only necessary for an external jpeg library, the builtin one
+// usually used on Windows doesn't use the type boolean, so always works.
