Comment (by nigel):

 This illustrates the problem:
 {{{
 #include <cstdlib>
 use namespace std;

 int main()
 {
     long long test = -1;

     if ( abs(test) > 1 )
         exit(-1)

     exit(0);
 }
 }}}
 On any GCC 3.3 machine (My Mac, Sparc Solaris, ''et c.'') it gives the
 error when the namespace line is there, but not if it is commented out. I
 am guessing that only after 3.3 they decided to have a decent set of std::
 overloads, but then they stupidly also added an llabs() in the same place.

 I was hoping that something simple like casting to a double would work,
 but surprize-surprise, that is ambiguously overloaded in GCC4 or later (in
 thye same way that llabs() is).

 #ifdef GCC_VERSION is just too ugly - I think I will define a local
 myAbs() instead?
