I managed to compile all correctly and make it work on my software on 
x64 using CTL-1.4.1 and OpenEXR_CTL-1.0.1.  The Half.dll linker error 
was related to not having rebuilt CTL.

The CTL git HEAD compilation errors are definitively due to a bug in 
MSVC 2010, as all exists in the files and the code is valid (works on 
Linux without a hitch), so I am for now sticking to CTL-1.4.1.

Now, I have tried compiling for win32.  I face a linker error in Win32 
IlmImf.  It complains about _compress and _uncompress not being found.  
I checked that I am linking against a Win32 zlibwapi.lib and the 
_compress/_decompress functions are present there.  I compiled 
zlibwapi.dll myself so I am really puzzled as the cause.
