temporary storage. In the old NFS code it wasn't at all clear if the value of `tl' was used across or after macro calls, but I'm fairly confident that the convention was to keep its use local. Each ex-macro function now uses a local version of this variable, so all of the double-indirection goes away. The only exception to the `local use' rule for `tl' is nfsm_clget(), which is left unchanged by this commit. Reviewed by: peter
