An easy place to do this is to compile trionan.c by itself. This is
done by defining the STANDALONE macro during compilation. I do not
know the exact syntax for the Win32 compiler used, but to give you
an example, I did as follows:

[breese stellifer:...trio/head/trio] cc -DSTANDALONE trionan.c -o
trionan
[breese stellifer:...trio/head/trio] ./trionan
Nan   : + FP_NAN          nan
PInf  : + FP_INFINITE     inf
NInf  : - FP_INFINITE     -inf
PZero : + FP_ZERO         0
NZero : - FP_ZERO         -0
PNorm : + FP_NORMAL       1
NNorm : - FP_NORMAL       -1
PSub  : + FP_SUBNORMAL    1e-309
NSub  : - FP_SUBNORMAL    -1e-309
NaN :  nan 0x000000000000f87f ( 1,  0)
PInf:  inf 0x000000000000f07f ( 0,  1)
NInf: -inf 0x000000000000f0ff ( 0, -1)
NaN :  nan 0x000000000000f8ff ( 1,  0)
PInf:  inf 0x000000000000f07f ( 0,  1)
NInf: -inf 0x000000000000f0ff ( 0, -1)
