Build error

Hello,

I am trying to build the latest nightly snapshot on windows2000, and
I'm getting the following error:

make[2]: Entering directory `/d/work/pgsql/postgresql-snapshot/src/port'

I have tried to ./configure with --with-includes=/mingw/include , and it
apparently got past the error, but later it complained that:

I believe there is something wrong with mingw or msys, and not with
the pgsql sources. Do you have any idea about what could be the problem ?
