graphics/blender: math.h: isnan(): error: controlling expression type 'unsigned int' not compatible with any generic association type

[O. Hartmann]

port graphics/blender doesn't compiler neither in CURRENT nor 9.2-PRE
for the moment. On CURRENT (FreeBSD 10.0-CURRENT #4 r254430: Fri Aug 16
23:23:08 CEST 2013 amd64), compilation fails with the belwo shown error
message - for roughly a month now. 

I think this is dur to some issues of inconsistency/incompatibility of
the math.h/cmath headers regarding the reported c++11 issues.


Since port graphics/blender doesn't compile on 9.2 nor does it compile
in CURRENT and the fact that the math.h isn't fixed in the 9.2-RELEASE
as I was told, the port should be marked broken.
