  According to the v4.2.4 manual, mpf_get_str can be called with a NULL in
  the first argument:
  
    If str is NULL, the result string is allocated using the current
    allocation function (see
    Chapter 14 [Custom Allocation], page 85). The block will be
    strlen(str)+1 bytes, that
    being exactly enough for the string and null-terminator.
  
  What I'd like to know is whether this block needs to be freed, and if so,
  how? Is it simply a case of
  
    free( ptr, strlen(ptr)+1);
  
That depends entirely on how the free() function you're using on your
system expects to be called.  The C standard library function surely
doesn't take any size argument.
