I think adding "-Drestrict=__restrict" to the compile line should fix
the problem.  In a few places, ImathMatrix.h uses restricted pointers.
Restricted pointers are standard in C99.  They are not officially part
of C++, but some compilers support them anyway.  In g++, the keyword
for restricted pointers is "__restrict".
