Mine is gcc-2.96-110.

I get a different error message, but since I'm a little vague on what 
C++ templates are all about, please confirm that I made the change 
correctly:

    return (unsigned char) (clamp (Math::pow<float> (x, 0.4545f) * 
84.66f, 0.f, 255.f));

Here's the new output:

makePreview.cpp: In function `unsigned char {unnamed}::gamma (half,
float)':
makePreview.cpp:86: use of class template `template <T> struct
Imath::Math' as expression
makePreview.cpp:86: parse error before `::'
