The C99 program:
fails because the compiler's code generation for conversions from 
floating-point (FP) to integer is wrong.  In some cases, some FP
exception flags are raised when no FP exceptions should happen.
In other cases, FP exception flags are not being raised when they
should happen.

Command line options:  -std=c99 -fmath-errno -O0 -lm
