I always found it curious that the first C standard (1989) was published
four years after IEEE-754 (1985) get only briefly mentions the latter, in
the description of float.h.  

At the time it certainly could not mandate conformity to 754 because most
hardware did not support 754 arithmetic -- but one might though there could
have been a 'should' or two... :-).
