This seems to be related to the problem with FLT_EPSILON being undefined in some
places and <float.h> being "missing" sometimes.

Dunno if anyone can shed any light on this - but indeed, the classic C header
"/usr/include/float.h" is not present under my SuSE 6.4 system...and none of
the other headers in /usr/include or and of it's subdirectories seem to have
a definition for FLT_MAX.

In desperation, I wrote:

#include <math.h>

float x = FLT_MAX ;

...and ran:

  % cpp test.c

...which suggested that the definition of FLT_MAX was in

   "/usr/lib/gcc-lib/i486-suse-linux/2.95.2/include/float.h"

A SuSE specific directory?!?  Yuck!

Can *anyone* tell me why this might be fouling up under
Mandrake 7.1?

The first couple of lines of /usr/include/plib/sg.h are:

  #include <limits.h>
  #include <math.h>

I've had to avoif doing a:

  #include <float.h>

...under Linux *because* that file has ceased to exist in the 'normal' places.

My head hurts...somebody make it stop!

There must be some weird kind of magic going on inside the compiler
somewhere.
