Subject: Fix some uninitialized variable bugs
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=cf26b3e8a4d056c93860f4292d9cd5fc5cb00890;p=xboard.git

Fix some uninitialized variable bugs

The writing of Seirawan castling rights in FEN was still dependent on a
now unused variable, and encountering a VariantMen tag in a PGN file
could have created the misconception the memory was full.
