os.findlib Windows bug?

[namiestew]

I am not too sure if this is a bug but I found that the additional paths passed to the os.findlib function is not being concatenated with the correct delimiter for Windows which results in nothing being found.

As can be seen in line 149 and line 154 of os.lua file, the paths are being delimited with a colon instead of a semicolon for Windows. This will result in invalid paths being used in os.pathsearch and no results would get returned. Is someone able to confirm if my observation is correct?

I thought this was odd, too, especially since the rest of Premake seems to be so VS- (and thus Windows-) focused. At first, I thought it's because this is only an internal path string, and the distinction would be handled within os.pathsearch; but there it specifically ignores : on Windows because it's a drive separator.

But! if you don't specify additional paths, everything works fine, because the PATH environment variable is essentially passed through (from get_library_search_path) and used unchanged.
