[gnugo-devel] trevor_1_10.2

[Trevor Morris]

Here's a patch that corrects the cygwin problem w/ dragon-data,
and a couple of related problems.

Relatedly, the following problem still exists under cygwin.
Seems to be a problem with sscanf and %n under cygwin in
gtp_main_loop in gtp.c, but I've still not nailed it down.

loadsgf
? cannot open or parse 'äûÿƒÄ?%ökƒ0?.'

loadsgf x
? cannot open or parse 'x'

loadsgf
? missing filename

Notice how the (correct) missing filename error message comes up 
only after calling loadsgf with an invalid file.
