Subject: Implement yynewstr entry point in new parser
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=065c7fdfab3182e5d5117a4c11b71eca40b70e12

Implement yynewstr entry point in new parser

This entry point, used for parsing an ICS move list, was forgotten, and
was still an empty routine. This made XBoard crash when observing an ICS
game.
