Hi,
Here is my first patch, it's nothing special, but I have to start
somewhere, This patch simply removes the warning messages like the
following:
"warning: using `%eax' instead of '%ax' due to `l' suffix."
by changing all the 'l' suffixes to 'w' and adding 'w' where it is
missing.
This patch applies to 2.3.24.
