It seems that 8 unexpected failures may be fixed by introducing the 
declaration (or definition?) of double abs(double) in stdlib_iso.h. But 
it is already defined in math_iso.h. I don't know what logic should be 
used to avoid defining it twice. I'm not sure about other failures.
Two of them are ld - specific, it seems they occured because /usr/bin 
was earlier in my PATH than /usr/gnu/bin.
And I'm not sure about several other.

There are some more error messages from dejagnu logs:

If you want I can upload the whole test log somewhere.
