This is because g++ has builtin definitions of the math.h functions in
::. When I compile

namespace std{
#include <math.h>
}

main()
{
  sqrt(9.0);
}

with

g++ -fhonor-std -fno-builtin d.cc -o d

I get

d.cc: In function `int main()':
d.cc:7: warning: implicit declaration of function `int sqrt(...)'

When I compile

namespace std{
#include <math.h>
}

main()
{
  std::sqrt(9.0);
}

instead, it compiles. The real fix, of course, is that the builtin
functions should be in std:: if it is honored. Thanks for your report.

Hope this helps,
Martin
