dnl  Usage: r0 ... r31
dnl         f0 ... f31
dnl
dnl  Map register names r0 to $0, and f0 to $f0, etc.
dnl  This is needed on all systems but Unicos
dnl
dnl  defreg() is used to protect the $ in $0 (otherwise it would represent a
dnl  macro argument).  Double quoting is used to protect the f0 in $f0
dnl  (otherwise it would be an infinite recursion).
