Replacing the signature in the SetFilePointerDLLCALL and
GetFileSizeDLLCALL (of the code I wrote) makes no difference, the
SetFilePointerR and GetFileSizeR (as I defined them) still work:
   SetFilePointerDLLCALL=: >@{.@('kernel32 SetFilePointer i x x *x i'&(15!:0))
   GetFileSizeDLLCALL=: >@{.@('kernel32 GetFileSize i x *x'&(15!:0))

Do you mean that using

SetFilePointerR=: >@{.@('kernel32 SetFilePointer i x x *x i'&(15!:0))
GetFileSizeR=: >@{.@('kernel32 GetFileSize i x *x'&(15!:0))

will work on win64 without the need of long64to32 and long32to64?
