postgres 7.4 build for win

Hi,

I am trying to build postgres 7.4.5 on windows (200) on
mingw/msys env. I have installed win32-pthreads to
enable-thread safet feature. Couple of issues that I
wanted to check:.

i) The configure was --enablethread-safety flag for the
platform (it was complaining CANNOT enable threads on your
platform). I copied src/template/linux to
src/template/win32 (most of the contents seemed thread
related) and the error was gone. Does this fix seem
reasonable.

ii) I am now getting an error that postgres doesnt have
native spinlock on this platform and to disable the
spinlock. Is this the expected behavior for the platform.

Thanks..
Amin
