error building ilmbase-src (kde-4.8 / kde-4.7)

[Stuart Dickson]

I've been trying to build the OpenEXR library against kde-4.7. (having 
to import the portage folders for the libraries)
I've encountered a problem building the dependency: ilmbase

This error occurs in both the kde-4.8 branch, and the kde-4.7 branch 
(where I've copied the portage folders for ilmbase-src and openexr-src into)

The output is as follows:

I can see that an empty toFloat.h file is created in the 
work/msvc2010-RelWithDebInfo-1.0 folder
Interesting that the eLut.h file seems to be generated in a similar 
fashion, but without issue.


Thanks,
