lapack-3-2.2 is already available in cygwin, look for

liblapack-devel              3.2.2-2
liblapack0                     3.2.2-2

atlas is not what I suggest to learn a unix build process.
xconfig is the configuration program built by the atlas configure, so
it is not cygwin specific.

Wich atlas do you want to build ?

Here
http://matzeri.altervista.org/cygwin-1.7/atlas/index.html

you will find a cygwin source package for 3.9.33 : atlas-3.9.33-1-src.tar.bz2

To build atlas for cygwin:

0)  install also cygport from cygwin setup
1)  "tar -xjf atlas-3.9.33-1-src.tar.bz2"
2)  "cygport atlas-3.9.33-1.cygport almostall"

the outcome should be the cygwin atlas package for your processor, the
build tree separated
by the source tree and a full log of all the operations.

In theory should be easy to adapt to the latest 3.9.41, but I never
had time to try it.

Regards
Marco
