Log:
Always use c99 float function overloads when using Dinkumware with Visual C++,
as it doesn't always have the C++ overloads. Fixes #2264.

  Reinstate the old choice of float functions on Dinkumware for all compilers
  other than Visual C++.
  
  It turns out that Borland uses Dinkumware but doesn't have the C99 float
  overloads, so it only seems realistic to assume their existence on Visual C++.
  Refs #2264.
