Upx is great...I have even comprerssed some of the other executables on
my system with it....but,you can get even smaller .exe's using the
-s switch AND upx.

Plain compile of a simple program......120503 bytes
With the -s switch               .......58880 bytes
plain compile + upx              .......34028 bytes
-s switch + upx                  .......34008 bytes

Its not a huge difference with this particular program
so i will try another.

Plain compile of a simple program......537804 bytes
With the -s switch               ......289792 bytes
plain compile + upx              ......123416 bytes
-s switch + upx                  ......123400 bytes

hmmmm....I thought i was making a point but it looks
like you only save a few bytes with using both...still
there are a FEW bytes saved....

I am gonna try one more thing....
Ok i tried the -s switch and the -O2 switch AND upx.
ended up with..........................119268 bytes

Now,that IS a little better...Now someone is gonna
tell me that the -O2 switch is some kind of bad thing
that i will wish i hadnt ever heard of......

Hope i helped.....
