#11496: config test math_info has issue with INFINITY

     Type:  Bugs                       |     Status:  new
Milestone:  To Be Determined           |  Component:  config
  Version:  Boost 1.56.0               |   Severity:  Problem
 Keywords:                             |
---------------------------------------+-------------------------
 The config test math_info contains:

 #ifdef INFINITY
    PRINT_EXPRESSION(INFINITY);
 #endif

 The test expects this program to compile/run cleanly.  This may not be
 case.  According to the standard:

               INFINITY

        expands to a constant expression of type float  representing
        positive  or  unsigned  infinity,  if  available;  else to a
        positive  constant  of  type   float   that   overflows   at
        translation time.192)


 So...it's perfectly valid for this test to fail at compile-time.

 Not sure how to easily fix this...

 Thanks,

 Ed
