Release Notes:
  1) no DLL is currently provided - so all client utilities are much larger 
executables than those found in Yuri's MySQL v4.1.7
  2) no libs\*, include\* are provided to reduce the package size - these 
are available on request
  3) built with libc06 CSD1 so libc061.dll is required - this can be 
downloaded from ftp://ftp.netlabs.org/pub/gcc/libc-0.6.1-csd1.zip
  4) this has currently had very limited testing - but it is running now on 
my server and being used successfully with my build of PHP 4.4.2
  5) All bug reports should be submitted via the bug tracker at 
http://mantis.smedley.info

Users of MySQL v4.1.7 can simply copy their data directory from the 
mysql41\data directory to mysql5\data and restart with the new mysqld.exe 
and it should work fine.

A *big* thanks to Yuri Dario who provided his patches for MySQL 4.1.7 which 
were the basis for this updated port.  You can checkout (and support) 
Yuri's efforts via his website at http://www.os2power.com/yuri
