Math headers (math.h, math_iso.h) appear  to be correct. It  seems that 
not patching them allows the c++0x test with abs(double) complete 
successfully.

Now I'm running G++ tests once more time...
Hint: you shold define liconv to "" i "-lc" for iconv-related tests to pass:
$ export DEJAGNU=~/.dejagnu.exp
$ cat $DEJAGNU
set libiconv "-lc"
