Actually, the 80387 and the '87 FPU in all other IA-32 processors
do use IEEE 745 double-precision arithmetic when requested to do so.
The problem is that GCC doesn't request that it do so. It's a long
standing problem with GCC that will probably never be fixed. You can
work around this problem the way the Microsoft C/C++ compiler does
by requesting that the FPU always use double-precision arithmetic.
That way your answers are only wrong when you use long double or float.
