Your changes seems better now except AFAIK you not necessary normalize vector
before calculating cross product (you only inrease floating point error at
this moment) in HFCreate_() macro. Consider below example:
#include "strings"
#local A=<126,45,33>;
#local B=<63,12,7>/1000;
#declare C=vnormalize(vcross(vnormalize(A),vnormalize(B)));
#declare D=vnormalize(vcross(A,B));
#warning VStr(C)
#warning VStr(D)
