The grammar
procoptionlist:
{ $<pol>$ = newProcOptionList(); }
procoption
{ $$ = $<pol>1; }
| procoptionlist procoption {$$=$1;}
| procoptionlist ',' {$$=$1;} procoption {$$=$1;}
;
procoption:
MAIN { if(setTristateAttribute(&($<pol>0)->main,1)<0) YYERROR; }
;
so the procoption can be separated by either blanks or comma.
I would be interested in knowing other solutions to this ...
