| |
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.
