The code snippet supplied was a heavily reduced sample piece. We tried
to keep our sample code as simple as possible to avoid confusion. The
state machine does nothing useful except highlight the problem we
encountered with a much more complex state machine.

The sample code is very small so I send it attached with this email.
There are two zip files, the one called class_test.zip contains the
code which triggers the problem. structversion.zip is essentially the
same code, except that state Active is now declared as struct. This
version compiles without a problem.

Sorry, this was my first post to this forum. I've noticed it from other
posts to this list in the mean time.
