Hi!

I've tried to build Python 2.7.3rc2 on cygwin and got the following errors:

$ CFLAGS=-I/usr/include/ncursesw/ CPPFLAGS=-I/usr/include/ncursesw/ ./configure
$ make

Failed to build these modules:
_curses            _io



Then tried to see if the problem is sovled, fetched the source from 
https://bitbucket.org/python_mirrors/releasing-2.7.3 and got another one:

$ CFLAGS=-I/usr/include/ncursesw/ CPPFLAGS=-I/usr/include/ncursesw/ ./configure
$ make

Makefile:1456: recipe for target `Modules/signalmodule.o' failed

Reporting here, because bugs.python.org refuses connections currently.

Just in case
CYGWIN_NT-6.1-WOW64 ... 1.7.11(0.260/5/3) 2012-02-24 14:05 i686 Cygwin
gcc version 4.5.3 (GCC)
