RE: DDD on cygwin - 2

[Chuck . Irvine]

Jong,

Excellent! Thanks! I'm configuring DDD now. Do you know if the files you
mention changed in 3.2.92? If so and I want to use this latest version,
I suppose that I should get 3.2.91 sources, generate patches from your
replacement files, and try to apply the patches to 3.2.92. Do you think
this is right? Thanks

Chuck
