#224 Default transition in Default state generates unused function

[David Rea]

When building with gcc -Wall, generated state machine source file contains an unused _Default() function. To reproduce:

$ git clone https://git.code.sf.net/p/smc/git-code smc-git-code
$ cd smc-git-code/examples/C/EX1

// Edit AppClass.sm to add:
//   Default
//   {
//              Default         nil             {}
 //   }

$ java -jar ../../../bin/Smc.jar -c  AppClass.sm
$ gcc -Wall -g -I../../../lib/C -o checkstring AppClass_sm.c AppClass.c main.c

// Output:
// AppClass_sm.c:39:13: warning: ‘AppClassState_Default’ defined but not used [-Wunused-function]
//   39 | static void AppClassState_Default(struct AppClassContext *const fsm)
//      |             ^~~~~~~~~~~~~~~~~~~~~

Many organizations standardize on running gcc with -Wall -Werror, requiring file-wise workarounds to disable this warning. All macros defined to AppClassState_Default() are re-defined to use Map1_DefaultState_Default().

Fix will appear in SMC release 7.2.0.
