Ok... the smt.inc macro: PKG_SMT_2PAD_MM100

has the following lines:

define(`R1',    `eval(($9  * 10000)/254)')
define(`R2',    `eval(($10 * 10000)/254)')

(and others)... presumably this means that the term R2 and R1 are
becoming expandable macros, hence confusing the heck out of any later
macro which uses that name.

I guess it might be a string escaping problem in the ACY macros, or
something wrong with PKG_SMT_2PAD_MM100, in that it should keep its
define's local.

Does anyone who actually knows M4 want to step in and help here... I'm
learning it as I go!
