It can't possibly work. Please test it properly before resending it
once more.

msiexec: msiexec also supports options using a hyphen [RESEND]

I did test it, and for the option I tested it does work.  I should
have done more thorough tests though, because looking more closely at
why it might not be correct, I see that I don't need to advance the
second string because we don't send in the slash or hyphen:

+    /* skip over possible hyphen or slash */
+    return msi_strequal(str1 + 1, str2 + 1); << str2 + 1 should just be str2
...
-   if(!msi_strequal(argvW[1], "/@"))
+   if(!msi_option_equal(argvW[1], "@")) << no hyphen or slash

It was working before because we call
MultiByteToWideChar(...,str2,-1,...) which will return length 1
(null-terminator) for all options.  We then try to compare str1 and
str2W using the length value returned from MultiByteToWideChar minus 1
(zero) which always returns CSTR_EQUAL.  I was testing to see if it
worked with /i and -i, and that did the install correctly because the
install option is the first case that uses msi_option_prefix.  Any
other value would cause the install too, which is why the testing was
insufficient.
