predefined macros and "MAXFLOAT"

[Robert Seals]

Hello,

<math.h> defines MAXFLOAT as (*((float *) (&SFPMAX))), and SFPMAX
is an extern unsigned int. So, it's impossible to do something like

const float        lims[] = {1.0, 2.5, MAXFLOAT};

because MAXFLOAT isn't constant.

I suppose there's nothing really wrong with this, but it kinda
bugs me that it's a variable. What do YOU think? Should it
be just #defined to be the real value, or is this tricky business
better?

And another thing, I can't find anyplace (even under "Predefined Macros"
in the info explorer) what sort of groovy things are defined by the
compiler - there must be something like "AIX" or "(C) IBM Corp" or
something, eh?
