A note on MathLink: cygwin Makefile for building addtwo.exe

Somehow I could not get the instructions for
"Building MathLink programs with Microsoft Visual Studio"
http://reference.wolfram.com/mathematica/tutorial/MathLinkDeveloperGuide-Windows.html
(i.e., steps 39. up to 66.) to work.
Did anybody do this successfully? With or without VS-service packs?

Instead I played with cygwin, and just a GNU "make" of the Makefile
below will nicely build addtwo.exe on Windows XP.
This works similar for C++ projects.
