Building Postgres under Cygwin

This weekend I d/l 7.3b3 and successfully built/installed it with my Cygwin installation under XP. 
Last night I needed to update a few cygwin packages and today I d/l 7.3b4. Suddenly my build 
failed for b4 so I went back and tried to build b3. It failed as well (complaining about off_t being 
redeclared as a different type of symbol) leaving me to believe that Cygwin must have updated my 
header files along with the things I asked for. Unfortunately I can't seem to get back to a 
configuration that'll let me build it successfully. Has anyone else gotten 7.3b4(or 3) built/running 
under Cygwin and could they tell me what their version information on the cygwin packages are?

	thanx much & later,

PS: FWIW - both versions build fine under Linux.
