Finally solved by adding a lot of #ifdef. ^^
According to http://www.gnu.org/software/libc/manual/html_node/Status-bit-operations.html
:
Each constant is defined if and only if the FPU you are compiling for
supports that exception, so you can test for FPU support with
'#ifdef'.
That's what I did. I found an old patch here which make me think it
was the good solution :
http://repository.timesys.com/buildsources/g/glibc/glibc-2.15/glibc-2.15-coldfire-non-fenv.patch
So here is the patch if you want to integrate it.
All builds fine now. :)
Thanks,
Gilles
