I am a Comp. Sci. student at Ryerson Polytechnic
University in toronto. I am in the midst of a software engineering project
that involves the development of a (possibly) relational database on a RedHat
6.2 development environment, we are coding in C. now my question is, how

Hello!
Here is a patch to make the current snapshot compile on Win32 (native, libpq
and psql) again. Changes are:
1) psql requires the includes of "io.h" and "fcntl.h" in command.c in order
to make a call to open() work (io.h for _open(), fcntl.h for the O_xxx)
2) PG_VERSION is no longer defined
