graphics/blender: isnan(cineon->element[i].refLowData)) - error: controlling expression type 'unsigned int' not compatible with any generic association type

[O. Hartmann]

Compiling port graphics/blender ends up in the follwoig error due to an
compiler error on FreeBSD 10.0-CURRENT ( FreeBSD 10.0-CURRENT #0
r253917: Sat Aug  3 20:33:55 CEST 2013). 

Prior to build (or try to build/upgrade) I had to apply the patches
(last in row) suggested in PR ports/180650
(graphics/openshadinglaguage), since graphics/blender relies on
graphics/openshadinglanguage, openshadinglanguage doesn't compile with
port devel/llvm which is stuck at LLVM 3.2 (CLANG on CURRENT and
9.2-PRE is in the meanwhile CLANG 3.3!) and needs to use devel/llvm33.

I think the problem occuring during compilation is due to some strange
implementation issues in math.h / cmath discussed earlier in the list.

Port graphics/blender doesn't compile on both, CURRENT (as reposted
above) and most recent and up to date FreeBSD 9.2-BETA (FreeBSD
9.2-BETA2 #0 r253884: Fri Aug  2 14:52:14 CEST 2013), dropping the same
error.
