I have been developing a mixed python / C++ program which uses SWIG to
handle the interface.  This worked fine until I updated binutils to
20060709-1.  Then when the python script tried to load the DLL generated
with the help of SWIG, the following error message appeared:
Traceback (most recent call last):
  File "main.py", line 13, in ?
    from py_extend import *
  File "/c/usr/projects/py_extend.py", line 5, in ?
    import _py_extend
ImportError: Permission denied

All file permissions looked o.k.  Restoring binutils to 20050610-1 fixed
the problem.

Is the new binutils broken?  Is there a new ld option I should be using?
Or perhaps I was getting away with bad behaviour before and the new
binutils is punishing me?  I have been generating the DLL simply with "g++
-shared $(OBJECTS) -o _py_extend.dll".
