SHORT ANSWER:

  Well, I'm guessing that the short answer is to hack in:

      #include <float.h>

  ...into PLIB's src/sg.h, to re-build and re-install PLIB, and then
  to try again...but that doesn't compile on my Linux box.

LONG ANSWER:

  OK - I'm officially confused.

  1)  I always used to use 'math.h' which defined FLT_MAX.
      /usr/include/math.h *uses* FLT_MAX - so that ought to be OK.

  2)  That stopped working in a recent release - because it's
      actually defined in 'float.h' which has ceased to exist
      (at least under SuSE Linux 6.4).

  3)  At the top of 'values.h' it says:

      /*
        This interface is obsolete.  New programs should use
        <limits.h> and/or <float.h> instead of <values.h>. */

      ...but float.h has 'gone away' and 'limits.h' doesn't
      define it either.

  4)  At the end of 'limits.h', it says this:

      #if defined __GNUC__ && !defined _GCC_LIMITS_H_
      /* `_GCC_LIMITS_H_' is what GCC's file defines.  */
      # include_next <limits.h>
      #endif
 
      What the heck is '#include_next' ??!?

Aaaarrrggghhhhh!!!!

Anyway, somehow (despite FLT_MAX not being defined in ANY header file
I can find), my code compiles without <float.h>  ... I suspect that
these tokens are perhaps hard-coded into the C/C++ compiler so that
cross-compilation can work or something like that.

Does *anyone* have a clue?
