apparently my understanding of '{FLT,DBL,LDBL}_{MIN,MAX}_EXP' ahs
been wrong and thus proven by many and there change it back to
what it is meaning explained in http://www-ccs.ucsd.edu/c/float.html .
also fix spmath to use it's own consts instead of (now) off by one
float.h values thus to avoid any kind of binary changes.
