/* APPLE LOCAL file ptmf casts --bowdidge *//* In gcc-4.0 and beyond, kexts are not permitted to cast   pointer-to-member- functions into pointer-to-functions.     These casts should be flagged as a hard error if   -fapple-kext is an option for the compile.  -fpermissive shouldn't permit   this, either.  This checks for OSMemberFunctionCast in the error message   because the error advises developers to use that function to replace   these casts.
