[Proj] Problem with program on Windows

[Frank Willett]

I'm running Windows 7 Ultimate 64 and have cygwin installed.

I downloaded the proj.4 Windows binary distribution and tried the following command:

proj.exe +proj=utm +ellps=clrk66 +lon_0=0 +lat_0=0 +x_0=500000 +y_0=0 +units=m

expecting an answer of (500000.00, 0.00) and got (166017.00, 0.00)

I then tried:

proj.exe +proj=utm +ellps=clrk66 +lon_0=0 +lat_0=0 +x_0=0 +y_0=0 +units=m

expecting an answer of (0.00, 0.00) and I got the same answer of (166017.00, 0.00).

I then downloaded the source code and compiled/linked under cygwin and tried the above tests
again, obtaining (83398.20, 0.00) for both tests.

I sure hope I'm missing something obvious :-(

Any ideas?
