I was unable to download the latest copy of your source code from your 
respository, as you don't use one of hte tools I have (git, cvs, mecurial etc). 
As such, I have created this patch against your version 1.14


Given there is only a single line added to configure.ac, and the rest is in 
fp-aix.c, I doubt it will be hard to integrate.

I am still getting a linker error, but that is unrelated and probably more 
related to my setup, as I'm hitting a similar problem on other packages.

Personally I think this GSL/AIX issue is a gcc bug. One of the gcc developers 
asked me to submit it to the gcc bug tracker as a bug. But someone else has 
replied it is not a gcc bug.

It would appear that the float.h header file used by GCC is the same on every 
single platform, so it completely ignores anything that might have been put 
there by IBM, Sun, HP or whoever else. That seems wrong to me, but that's the 
way it is.

Let me know if these patches look ok to you. If you can integrate them to the 
next GSL release, it would be good.

As I say, I personally think it's a gcc bug, but I doubt I'll convince the gcc 
developers to fix it.
