Subject: [9front] [PATCH] cc: fix incorrect octal range condition in mpatov
Reply-To: 9front@9front.org
Precedence: bulk


This does not have any adverse effect, since yylex never calls mpatov
with a string with leading 0 (and not 0x) that contains non-octal
digits, but the condition was wrong regardless.
