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.
