Hi Angelo,
it is a change of behavior implemented by
upper stream developer 2 years ago
http://article.gmane.org/gmane.comp.video.graphicsmagick.help/857
so it is not my fault and you are the first to notice and complain :-) .
I will not change the behavior for cygwin, 
and the proposed workaround is the new expected way of working ;-)
Eventually to avoid the re-sampling of your jpeg image, with lower 
quality, you should use
gm convert -compress jpeg -define jpeg:preserve-settings test.jpg test.pdf
Regards
Marco
