[Bug-XBoard] We distribute wrongly compiled WinBoard binaries

[h.g. muller]

The current source does not work correctly when compiled with gcc+Cygwin,
which I use (with the -mno-cygwin flag) to generate the binary distribution 
and
installer package.

The u64Display format that is used (%lld) will not work to read all 64-bits 
in scanf,
and lead to a phase error of any following arguments in printf. This leads 
to incorrect
operation of node-based time controls, as they use the node count from the 
thinking
output, which now has an un-initialized most-significant word.

It seems that %I64u is needed here. This will produce compiler warnings for 
formats
not matching the variable, but it does read and print the u64 nodes count 
correctly.

Btw, I upgraded Cygwin, and the upgraded make now encounters a fatal error 
in the
makefile. A dependency of wgamelist.c on "config.h." is listed there (with 
an extra
trailing period!), and make now chokes on that. I see makefile.ms contains 
the same
error (for as long as they exist).
