/* APPLE LOCAL file kext 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.

   Radar 4025923, gcc-4.0 should ban kexts from doing ptmf to ptf
   conversions without OSMemberFunctionCast
