Subject: Fix time overflow bug
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=318bcd2df2a468bb49ff228d885351d70390a28a;p=capablanca.git

Fix time overflow bug

Time is stored in tenths of seconds, which makes it overflow. An attempt
to correct this in untenths() was ineffective, because of a signed/unsigned
mistake. (0xffffffff is not a large number, but equals -1!)
