Title: Give credit to PHP for the p_readlink function in posix_w32.c

Looking through the readlink in posix_w32.c function it looked very similar to the readlink function in PHP http://www.sourcecodebrowser.com/php5/5.3.3/link__win32_8c_source.html so giving them the proper credit as per the PHP license.
