Earlier, I thought GCC would eventually have to add some libc-specific

I forgot to say, this is with the latest version of the GNU Scientific library
(gsl-1.14).
The hardware used is
* IBM RS/6000 7025 F50
* 4 x 332 MHz 32-bit PowerPC CPUs
* 3 G

It looks to me that the GCC header file lacks several definitions that are in
the IBM header file (DEC128_EPSILON is another example). The size of the IBM

This is the IBM header file (/usr/include/float.h) from an AIX 5.3 system
Clearly this shows that
