[rrd-users] Build problem - Cygwin

te dependencies are, but normally the generated library (librrd.so)
knows what its dependencies are, so when you link -lrrd you do not
need to link the other dependencies as well because librrd will
pull them in automatically.

rrd_th is for multithreaded use ... but you are right, in the tcl
bindings, they actually do use rrd_th, so this should be fine ...

this was contributed, or I would be better able to help you ...
I do not realy use windows for server tasks, so my experiance is
rather anectotal in the area ... but if you want to sponsor a
project, I will be glad to conquer the beast for you :-)

cheers
