This bug is a placeholder that I put here to act as a reminder that mainline CVS GCC is unbuildable under CygWin32 because AutoGen will not build on that platform either.
Why do you need autogen to run?
So I can build the GCC mainline. The build system uses AG to create the top- level Makefile, among other things. That means, no AG, no go.
I think what I ment is why do you need Autogen when the toplevel Makefile is already generated?
Part of Fixincludes is AG'ed too, AFAIK.
But again you should not need it unless you change something.
