You're getting linker errors. If gcc behaves the same on Cygwin as it
does in its natural habitat, you probably ought to compile and link
instead with the command

    g++ -lgsl -Lc:/Programs/cygwin/usr/local/lib  \
    -Ic:/Programs/cygwin/usr/local/include c:/Downloads/simulate3node.cpp

(One line, of course. I put in a backslash as a line break so that it
would fit in this email.)

Notice that I simply changed -LLIBDIR with -L.

I'm not sure if the rng functions use GSL's CBLAS interface, but if
the above compilation command doesn't work, try linking with
-lgslcblas and -lm too. You might also want to read about GNU make and
Makefiles if you're going to be coding anything larger than a few
source files. Bruce Eckel's /Thinking in C++/ book available online
for a free (beer) download does a good job IMHO of giving a very brief
overview of Makefiles in its first volume. I forget which chapter it's
in, and I don't have the book handy, but you can probably find
Makefiles in its index.
