Hello,
Microsoft just decided to make Services for Unix a free download. The
package includes a lot of features to make a win32 computer more usable
in a mixed network. It also includes posix libraries, shells, even gcc
in a unix-ish build environment similar to cygwin (they call it
'Interix').
Perhaps with this new development it might be worthwhile investigating
getting postgres compiled using this build environment. This might be a
way to shortcut the win32 porting effort and keep the win32 specific
code in postgres down to an absolute minimum.
