[svn-r11087] Purpose: Bug fix.
Description: When converting floating-point numbers to integers and the values of
floating-point number are greater than the maximal value of integer, Cray X1 generates
floating exception.
Solution: Added a test in configure to detect Cray X1's exception. Set a flag to
indicate the machine that can handle overflow converting all floating-point to all
integer types. This flag should be set for all machines, except for Cray X1 where
floating exception is generated when the floating-point value is greater than the
maximal integer value.
Platforms tested: Cray X1 and h5committest.
