[PATCH v2 0/3] Resolve compiler warnings in master

[Samuel Holland <samuel@sholland.org>]

These three patches resolve some compiler warnings about mismatched
attributes, and restrict violations, and a macro redifinition.

Fixing the header prototype for ___errno_location does provide the
expected optimization improvement:

Before:
   text    data     bss     dec     hex filename
 675262    2146   11568  688976   a8350 lib/libc.so

After:
   text    data     bss     dec     hex filename
 674838    2146   11568  688552   a81a8 lib/libc.so

Changes since v1:
- Move the attribute to the prototype in src/include/errno.h
- Add patch 3

Samuel Holland (3):
  resolve -Wrestrict warnings
  use the correct attributes for ___errno_location
