I've received a bug report about KDE no longer compiling with EXR support with 
OpenEXR 1.6.0

Here is the report: http://bugs.kde.org/show_bug.cgi?id=148865

Basically, the problem is that this (from ImfStandardAttributes.h)
IMF_STD_ATTRIBUTE_DEF (utcOffset, utcOffset, float)
became
IMF_STD_ATTRIBUTE_DEF (utcOffset, UtcOffset, float)

Was this change intended? Will future versions of OpenEXR contain 
source-incompatible changes? 

The reason why I'm asking is to know how to protect this code (i.e. 1.4 and 
earlier, 1.6 and later, 1.6 only, etc)
