Call for list of working llvm-gcc revisions

I am having great difficulty tracking down a Cygwin llvm-gcc-4.2 build bug.

The main difficult I am experiencing is narrowing down which revision this bug first manifest.

Its somewhere between r96185 and r99293, I attempted to bisect this, but am getting building llvm-gcc revisions.

Does anyone have a list of building revisions between r96185 and r99293 please.

Many thanks in advance,
