[Swftools-common] Regeneration from flex/bison fails

[Jan Engelhardt]

swftools git (c514a78a66df841b79ef8da285a7e3dd3aba7e2b)
is not fully buildable from scratch:


$ cd lib/action

compile.h says
int swf4parse(void *b);
int swf5parse(void *b);

while tab.h has
#ifdef YYPARSE_PARAM

int swf4parse (void *YYPARSE_PARAM);
#else
int swf4parse ();
#endif
#else /* ! YYPARSE_PARAM */
