There is no need to disconsider the winmain case. C Always executes the=20
main function first.

In this case, the main function is the Windows OS. Windows then calls a=20
WinMain function (your program and/or others) when it allocates time for=20
it. This is considered "better" because if your program=20
stalls/crashes/infinite loops Windows can, after an allocated time period=20
take back control. Also in a multi-threaded environment some programs could=
=20
be CPU hogs. This forces them to behave.

This also makes it possible for a Windows program to receive messages=20
(keypress/mouse event) at any time during execution. That would be=20
difficult if not impossible in a linearly executing program.

In my experience this all sounds better than it actually works but...=20
that's the theory :)
