You are a bit ambiguous here.  Are you trying to compile "linux
binaries" of POSIX code?  For that you need a cross-compiler (about
which I know nothing).

Or are you trying to compile Windows binaries of POSIX code that is
often found on Linux systems?  In which case, you want to do
something like this.

  $ tar -xvf package-ver.tar.gz
  $ cd package-ver
  $ ./configure
  $ make
  $ make install

See the FAQ: Why doesn't su work?
http://cygwin.com/faq/faq-nochunks.html#faq.using.su

You are getting bash's default prompt.  See=20
  $ man bash
for how and where to customize your prompt.  (Though Gary Johnson's
advice about using a login shell may address the issue.)

I hope this helps.
