Re: Add option to cygstart to use CreateProcess as opposed to ShellExecuteEx

Agreed, sygstart serves a definite purpose, it's just not the fastest
launching straight executables, however...

I haven't until this point played with run.exe or run2.exe.  They
serve my purposes very nicely, so my little app isn't required.

Several machines, I assume due to the fact of how ShellExecuteEx
operates (resolving file types to executables, etc.).
