Some patches posterior to Python 2.7.3 are needed to build on Cygwin.
Namely fixes from the issues 9665, 14437, 14438 on Python issue tracker.

Comment:
Some further details:
- issue 9665 is still opened (and as it is back from 2010 and was not
modified since, I doubt it will be closed any time soon unless one of us
takes action);
- issue 14337 has been merged, but unfortunately after the Python 2.7.3
release;
- issue 14338 has been closed as invalid and marked as a Cygwin, rather
than Python, bug, why not... but what's sure is that it prevents to build
Python on Cygwin.
The patche we need from 9665 modifies configure.in (the other patch is
just issue 14337).
In order to take it into account in the configure script, I ran
"autoreconf -i" which also modified the configure script in several other
places, but in a seemingly harmless way.
It is mainly because I used a newer version of autotools than the one
originally used for the Python 2.7.3 release, and autotools decided
inbetween to prefix some variables names with "ac_".
A somehow less invasive solution would be to directly patch the configure
script, but I'm less inclined to do so than properly patching
configure.in.
The updated spkg is available at:
http://perso.telecom-paristech.fr/~flori/sage/python-2.7.3.p1.spkg
It builds correctly on Ubuntu 12.04 64 bits and is currently building on
my Cygwin 1.7.16 on Windows 7 64 bits (it failed a first time but because
of memory exhaustion which I often get while using Cygwin or MinGW).
I've search trac for a more recent spkg than the 2.7.3.p0 but did not find
anything.
If I missed some tickets including such an spkg, please let me know or
directly rebase the patches proposed here.
