[PATCH] Optimization warning on Win32.

The default flags for cl.exe includes the -O1 option which enables
optimizations. Unfortunately, the Standard Edition of Visual Studio doesn't
support that option so outputs a warning each time we compile. The attached
patch removes the -O1 option if it detects that the compiler is the Standard
Edition. I made a slight fix to Configure.pl while I was at it. It turns out
that eval can return undef even if there was no error so it's not safe to
say 'eval $foo or die $@;'. Instead, we should say 'eval $foo; die $@ if
$@;' since eval guarantees that $@ will be a null string if there was no
error.
