hack to work around gcc 4.2 compiler warning; really we should not store static strings in char * pointers (they should all be changed to const char *).

LLMatrix3::orthogonalize test was failing; possibly due to new lib dependencies or architecture on the build machines? Trying updating expected float values to see if it begins to pass.

Updated expected values to match result of query on WolframAlpha.com (mathematica):
N[Orthogonalize[{{1,4,3},{1,2,0},{2,4,2}}],8]
