Bitcoin 0.4.0rc1 BETA will not compile in windows 7 using https://github.com/bitcoin/bitcoin/blob/master/doc/build-msw.txt

I have tried building it on my own, and end up with

C:\bitcoin\src>mingw32-make bitcoin.exe bitcoind.exe -f mak
efile.mingw
g++ -c -mthreads -O2 -w -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DWIN32
