Description:
------------
When file_get_contents() is used under Windows with the file:// wrapper, it gives the following error:
Warning: file_get_contents() [<function.file-get-contents>]: remote host file access not supported

The bug is caused by the following code in main/streams/streams.c (for PHP5-200408171230 it is on line 1457).

		if (protocol && path[n+1] == '/' && path[n+2] == '/' && path[n+3] != '/')	{
			if (options & REPORT_ERRORS) {
				php_error_docref(NULL TSRMLS_CC, E_WARNING, "remote host file access not supported, %s", path);
			}
			return NULL;
		}

The condition path[n+3] != '/'  works for UNIX filesystems only. On Windows absolute path does not start with a /, but a drive letter followed by ":", e.g. D:\projects\...

Reproduce code:
---------------
file_get_contents ("D:\projects\index.tpl");


Expected result:
----------------
No error messages.


Actual result:
--------------
Warning: file_get_contents() [<function.file-get-contents>]: remote host file access not supported...
