You should have sh.exe in /bin -- this is actually bash, but may be a v2
release. If you then downloaded the v3 update, which is recommended,
then you should also install it in /bin.

This is by design; MSYS accepts UNIX paths, with the root representing
the MSYS installation directory, (nominally c:/msys/1.0, as you have
installed it), and it translates these to their native equivalents, so

This is exactly as you've asked it to do; compile a file called /help.

You use UNIX syntax, in the MSYS shell, so to get the help, you use

It is very usable, if you use it correctly.

If you do need to run a program which insists on `/', rather than accept
`-' as the switchar, then you must double the `/'
This is documented, in the readme.rtf file which accompanies
MSYS-1.0.10; if you have started out with the MSYS-1.0.11 preview, I'm
not sure if you get this in the core package, but this question has
been asked before.
