/* Before SWIG 4.1.0 the `9%a` expression triggered:
*
* Error: Unknown directive '%a'
*
* The fix for that works by handling an apparent directive that isn't a
* recognised directive by noting down its name, emitting MODULO and then
* rescanning what follows, and if the parser then gives a syntax error we
* report it as an unknown directive.
*
* However the initial version of this failed to reset the noted down apparent
* directive often enough, so a later syntax error could get incorrectly
* reported. Here the syntax error in the declaration of `c` was confusingly
* reported as `Error: Unknown directive '%a'`. This was found and fixed prior
* to 4.1.0.
