Make more C++ compilers understand the signbit function
Several C++ compilers cannot handle std::signbit; use a work-around instead. Correct a namespace problem when using the same identifier Vectors_SGN for different precisions (real*4 and real*8). Correct kifpos implementation incorrectly on several architectures. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@29 105869f7-3296-0410-a4ea-f4349344b45a
