[Cbc] Compiling on Windows

[Wenchel, Seth]

Ted,

I tried again this morning with the same results.  I did an svn co of
stable/2.6 into a clean directory and did "./configure -C; make -j 24" under
cygwin.

Were you refering to changes made in a development branch?  Again, let me
know if you want me to send you logs or other output.
cheers
seth

Sooner or later any problem will get big enough that you can¹t solve it.
But it¹s nicer if you make it later.
