Ok I admit I did not see what I was expecting, but let's look at
things statically. Since you have vs.net, you should also have
dumpbin. First look at:

dumpbin /dependents ruby.exe

then look at

dumpbin /dependents mysql.so

In particular we want to verify that they are using the same runtime
dll's (probably msvcrt.dll which is from vc6). If they are different
that is probably the problem.
