[g++] namespace problem

[brent verner]

Hi,

  I'm working on the C compatibility headers for libstdc++-v3
(process detailed: http://www.cantrip.org/cheaders.html ). There appears
to be a buglet floating around somewhere in the compiler system that
(,I believe, wrongly) finds ambiguity with function calls defined
in separate namespaces.

compiling the attached program results in the following:

  brent$ g++ screwy-namespaces.cc -o screwy-namespaces
  screwy-namespaces.cc: In function `int main ()':
  screwy-namespaces.cc:31: call of overloaded `abs (int)' is ambiguous
  <internal>:31: candidates are: int abs (int)
  screwy-namespaces.cc:19:                 int std::abs (int)

Where does the <internal> come from?

Also, I have attached the output from 'g++ -E -dD'

Thanks for your help,
  Brent
