Subject: Reintroduce GCC/ICC rounding hack
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=a5c85d3cfcdd4992100fb7c77562778c40ae92b9;p=fairystockfish.git

Reintroduce GCC/ICC rounding hack

Unfortunatly the source of this issue is not in the
different handling of log(0) illegal value.

No functional change on MSVC.
