But if libgfortran relies on a C99 libm, then why does it reimplement all
those complex functions at all? They should already be present. And if it
needs them to be present under any circumstances, it better use some
internal names to avoid clashes like the one described here.

As I said: if they are present already (and with the correct signature!),
just use them instead of reimplementing them.

Which doesn't hold for old releases like IRIX 5 or Tru64 UNIX V4.0. But
even current O/S and compiler releases just now start supporting C99.
GCC has tried to accomodate non-bleeding-edge O/Ses for a long time, and I
don't see a good reason to stop this now.
