numpy fails to build on cygwin due to not using the correct fortran compiler

[mwhansen]

The solution is to add 'sage_fortran' to the beginning of the list of fortran compilers on the cygwin line in src/numpy/distutils/fcompiler/init.py

trac_7321-1.patch appears to already be part of numpy-1.3.0.p2 and I won't comment on it.

trac_7321-2.patch appears to be correct and I'll give it a positive review.

OTOH, comparing numpy-1.3.0p2.spkg in sage-4.3 with mhansen/numpy-1.3.0.p3.spkg shows a number of other differences which shouldn't be present:

• Various emacs backup files (*~) exist
• Various *.pyc files exist
• patches/cygwin-core-setup.py has been copied to src/numpy/core/setup.py
• patches/!init!.py has been copied to src/numpy/distutils/fcompiler/!init!.py
• patches/gnu.py has been copied to src/numpy/distutils/fcompiler/gnu.py
• patches/cygwin-lapack_lite-setup.py has been copied to src/numpy/linalg/setup.py
• src/site.cfg exists
• src/build exists
  Overall, your numpy-1.3.0.p3.spkg needs rerolling to only include the changes in trac_7321-2.patch

I've posted a new spkg based on p2 with only trac_7321-2.patch applied. That should address the above concerns.
