Okay then, this does the trick:

diff --git a/src/analyze.l b/src/analyze.l
index f55c676..392c9aa 100644
--- a/src/analyze.l
+++ b/src/analyze.l

-{Unicode}              {yylval=strtol(yytext+1,NULL,16);return(UNUMBER);}

 {Decimal}|{Octal}|{Hex}        {yylval=strtol(yytext,NULL,0);return(NUMBER);}
 <RVALUE>{Literal}      {return((yylval=ksymtocode(yytext))==-1?ERROR:LITERAL);}

Sorry for the ugliness, I just sticked to the prevailing coding style in
analyze.l.  Re-format as you wish :-)
