Subject: Fix regression with stdarg dspwrappers.
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=cbf4ad5e9942032a96215a4c7f095a4777bf0021;p=gnushogi.git

Fix regression with stdarg dspwrappers.

1be442641b610fa1b6172a38d9acffe2d22797b6 and
3f589711eb3ecc7644378d6a0f2f29bc4b4c7db9 are both broken, passing the
va_list inside another va_list to poor unsuspecting backend implementations.
