Well... why not having a minimum precision requirement ? something like this:
generic
  type Real is digits <>;

package Special_functions is
  ...
end Special_functions;

package body Special_functions is
  ...
begin
  ... [raise an exception here if precision is not enough]
end Special_functions;

Agreed - some Ada programmers have a double standard, and accept a much lower one for the C code used for binding. Sometimes they would complain about formatting of comments in Ada code and and just ignore the mess of some old "1980's home-computing-like" +/- equivalent C code...
