           User-installable exception handlers

           Static redefinition of matherr() is useful only for statically linked
           libraries. When Libm is built as a DLL, the Libm's matherr() is already
           loaded into the DLL and (statically) linked.  In this case, the only way
           to replace the library default matherr() with your matherr() is to use
           the matherr() exchange functions (see description below).

           1. In user code, implement your own substitute matherr() function.
           2. To install it, call __libm_setusermatherr(), with your
              function as an argument. Note that the __libm_setusermatherr()
              returns the address of previously defined matherr. If you save
              the address, you can use it later to restore the original matherr().
           3. Your matherr() will now be installed! Your matherr() will be called
              instead of the default matherr().
