Missing posix package building on WinXP

I installed Cygwin, ghc 5.02.2, happy 1.11, and ghc-
5.02.2-src-1.tar on an XP system. Lacking lndir or 
similar executables, I mad a copy (cp -r) of the 
source tree to a new directory fptools and worked my 
way through the build instructions, ultimately doing:
$ ./configure
    :
$ make
    :
==fptools== make boot - --unix -wr;
 in /home/Martin/haskell/fptools/ghc/compiler

I also tried to just build sub-trees with similar 
errors.

Seems the windows binaries don't include the posix 
package. Is this just missing? Is there a way around 
this and build the compiler and utilities on XP?  I 
thought needing Cygwin anyway, there should be no 
problem to have posix support available.
