Question regarding the Wine Vs WineLib performance

[Tom Spear (aka Dustin Navea)]

This may sound like a stupid thought, and may have already been 
discussed (I couldnt attend wineconf), but doesnt g++ compile everything 
with -Ox upon request, so it is size-optimized (read: Compressed), and 
don't most people use that same flag on most compilations?  It seems to 
me that if the above 2 statements are correct, then the reason MSVC 
produces faster code than g++ is because MSVC doesnt compress it's 
output, you have to use something like upx to compress it, while keeping 
it executable, and then once that is done, the binary runs slower...  
Like I said, probably already discussed, and probably incorrect, but my 
2c either way.
