Dear all,

  Ron Chestnut found a sequencer parsing bug: pre-processor "#" lines were
not permitted between state set definitions. I have fixed this bug in Beta12.

  If you wish to fix this locally, you have to add a line to snc.y. The
section:

------------------------------------------------------------------------
state_set       /* define a state set */
:       STATE_SET NAME L_BRACKET state_list R_BRACKET
                                { $$ = expression(E_SS, $2, $4, 0); }
|       EXIT L_BRACKET stmt_list R_BRACKET
                                { exit_code($3); $$ = 0; }

|       error { snc_err("state set"); }
;
------------------------------------------------------------------------

has the blank line replaced to become:

------------------------------------------------------------------------
state_set       /* define a state set */
:       STATE_SET NAME L_BRACKET state_list R_BRACKET
                                { $$ = expression(E_SS, $2, $4, 0); }
|       EXIT L_BRACKET stmt_list R_BRACKET
                                { exit_code($3); $$ = 0; }
|       pp_code                 { $$ = 0; }
|       error { snc_err("state set"); }
;
------------------------------------------------------------------------
