configuration question

[Xiaoxu Wang]

sorry, the question I want to ask is

I got the following error when configuring Petsc,
'Configure' object has no attribute 'diff'  File 
"./config/configure.py", line 166, in petsc_configure
when it runs to (out,err,status) = 
Configure.executeShellCommand(getattr(self, 'diff')+' -w diff1 diff2'), 
line 56 in programs.py.



Hi,
     When I comfiguring Petsc under Windows and Cygwin, it always 
crashes when it is checking for diff. The path is correct. It could be 
the difference between '\' and '\\' in python causing the problem. How 
to solve this problem? Or can I skip checking for 'diff'? Thank you for 
suggestions.
