I haven't run into this.  If you can demonstrate the results you get on
linux and win32 using the "proj" or "cs2cs" commands, then I could
try and see if I get the same problem here on win32.

Producing binaries is a hassle, and so I do not make it part of
my release regimen.  The FWTools releases do include up to date
PROJ.4 binaries though I'm not sure if I include the PROJ.4 include
files and libraries for those wanting to build their own applications.


You might want to see if you get the same results with the FWTools
PROJ commands as you get from the ones you built yourself.
