Add x86-optimized implementation of the SHA-1 hash function, taken from
Nettle under the LGPL. This code will be enabled on kernels compiled for
486es or better; kernels which support 386es will use the generic
implementation (since we need BSWAP).
We disable building lib/sha1.o when an optimized
Add optimized implementation of the SHA-1 hash function for x86_64, ported
from the x86 implementation in Nettle (which is LGPLed).
The code has been tested with tcrypt and the NIST test vectors.

I've read the archive. I'm totally unconvinced by any of the fd

If for some reason you really can't do that (and a requirement for

Hello, I'm using -ck since... along time ago (I start using it with the

Actually I use 2.6.20-ck1 and I have no problems, even with things that

Can you please try to tell what your patch actually does.
As for the part added in the MAkefile you pass -lintl for Cygwin -
