Testcase minimization with Delta

[Daniel Berlin]

I found a neat program that can do testcase minimization for GCC.
It's a bit slow in it's current form, but this is from execing gcc, AFAICT. If 
someone rewrote it in C (not difficult, there are python and perl 
implementations of the algorithm it uses, and it's fairly straightforward)  
so that it could be linked with gcc itself, we could have an automatic 
test case minimizer program.

It's at http://www.cs.berkeley.edu/~dsw/delta.html

The python implementation is at http://www.st.cs.uni-sb.de/dd/DD.py
