Doesn't compile with recent dec tools

[FranckPachot]

I tried to compile on PG11 centos7 but got many errors:

#13 0.573 pllolcode.c:30:13: error: conflicting types for 'pllolcode_yyparse'
#13 0.573  extern int  pllolcode_yyparse(void *result);

#13 0.578 make: *** [pllolcode.o] Error 1

Then after removing the conflict:

If you have compiled it on recent version I'm interested. I find this project a good (and fun) way to show custom languages
