/*
* The following lex rule basically wants to recognize tokens
* that can change the current state of scanning source code.
* Evertime such tokens are recognized, the specific handler will be
* executed. All other tokens are treated as regular characters and
* they are all handled the same way.
* The tricky part was not to miss any specification in ANSI-C code
* that looks like a meaningful token but not a meaningful one and
* should be treated as regular characters.
* For example,
* c= '"';d='"'; printf("\"" "\(\)\\\"");
* c = ABgettext("Not a gettext");
* c = gettextXY("Not a gettext");
* c = ABgettextXY("Not a gettext");
