One patch per email, please. Also, the subject should be more descriptive.
The first one doesn't look much better than the second one (which was already rejected). sizeof(array)/sizeof(array[0]) is a constant expression; any optimizing compiler worth its salt will optimize that for you. (And I would know, because I work on LLVM and Clang.)
The first part of that patch (against dlls/kernel32/console.c) might be a bit more promising, though, since it hoists a computation that isn't constant at compile time but is constant for the duration of the loop; but again, any good optimizing compiler would be smart enough to do that, too. Oh, and you forgot to actually declare the variables that hold the hoisted values. Those assignments don't count, because:
a) You never gave them a type. That's an error in any C compiler (C89, C99, etc.) I'm not even sure a K&R compiler would take that. b) Wine is written in C89 (with some GNU extensions scattered throughout, but generally we try to write portable code around here); that means (among other things) all variable declarations must come before other statements.
Did you even try to compile Wine with these patches?
