If you want to modify piece of code X, then code in the same style as 
piece of code X.  Then piece of code X will all be written in the same 
coding style, and will be less eye-scratchy.

Use a prefix for your functions to make it easier for people that didn't 
write the code to find, and to avoid duplicate elf symbols for non 
static functions.  If you don't like SHELL_ then use shell_.

There's already a mismash of coding styles in Wine, and the last thing 
we need is more.
