Hi,
I had a bit of trouble compiling memcached for windows using mingw32
(and some issues remain) but I want to share the results in case
somebody else struggles with this. I used the following toolchain
gnuwin32 diff 2.8.7-1
gnuwin32 patch 2.5.9-7
mingw32 w32api 3.13
mingw32 mingwrt 3.15.2
mingw32 gcc-core 3.4.5-20060117-3
mingw32 binutils 2.19-2
Host operating system was Windows Server 2003.
I used memcached 1.2.1 with libevent 1.4.9 and the following patches
from [1] to get basic Windows support. To get it compiling with
mingw32 I had to add the following patch

As I said some issues remain and I hope you can help me resolve them:
--( slabs.c )--
memcached\slabs.c: In function `slabs_alloc':
memcached\slabs.c:218: warning: use of cast expressions as lvalues is
deprecated
--
The warning above should be easy to fix but i have no idea how to get
_set_errno working with mingw32. I read a couple of threads on the
internets about it (with solutions consisting mainly of magic like
[2]) but I hope there's an easier way of doing it

Hope somebody of you has an idea :-)
