[Bug-gnubg] rollout.h bug in 0.14.3

[BENJAMIN WILLMORE]

Hi,

GnuBG fails to build with GCC on Mac OS X 10.4, with the 
error:

rollout.c:222: error: static declaration of 'nSkip' 
follows non-static declaration
rollout.h:62: error: previous declaration of 'nSkip' was 
here

Seems fair.  Changing the rollout.h definition to static 
fixes it.
