I pushed some trivial fixes for the sh!tload of compiler warnings I got 
from the format.

For memrchr, my man page says to define _GNU_SOURCE before including 
string.h but that did not help. After looking at the header I define 
__USE_GNU instead, and undef it after including string.h. Not sure 
what's up with that?

When building with the -native target and no icc-precompiled intrinsics, 
I get the following benchmarks:

Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE
Raw:	10961K c/s real, 10961K c/s virtual

Benchmarking: Raw SHA-1 (taviso sse4 build) [rawsha1_sse4]... DONE
Raw:	11963K c/s real, 11963K c/s virtual
