when is a double float nearest infinity ?

[Christian Bruel]

I found the answer to my second question : I just needed to include 
<fenv.h>. Attached a fixed version of the example. But I'm still puzzled 
by the first question (why mdmax+dmax) gives infinity ?

attached a modified version of the test program, compiled with
gcc testinf.c -pedantic -ansi -mieee-fp -lm -Wall -O2

I also tried to compile with -moft-soft to check the libgcc behavior but 
that lead to undefined `__eqdf2' `__adddf3' references.

thanks for any help

Christian
