Finally, as part of installing the mingw32 compilers, remember to add

find the compilers later.

* Select the mingw compilers
In your cygwin window, if you type "which c++" you might get the
response path "/usr/bin/c++" which is the cygwin compiler. This is not
the one we want to use, however. Tell the shell where the mingw
compilers are by setting the search path like so:
$ PATH=/cygdrive/d/mingw-2.0.0/bin:$PATH
This assumes that you installed mingw in D:\mingw-2.0.0. The actual
programs are in the bin directory under the root. After this command,
check that you are now getting the right compilers with this "which"
command:
$ which c++
