For the terminating null pointer of the functions mpfr_inits,

mpfr_inits2, mpfr_clears, always use the type mpfr_ptr (no longer
void *). Updated the description of these functions in the manual
(mpfr.texi). The reason is that the C standard does not guarantee
that (void *) 0 has the same representation as a null pointer to
a structure (and even the same size). In most C implementations,
the representations are the same, but one never knows (dynamical
checking is also always possible)...
The change has been done with: perl -pi -e \
  's/(mpfr_(clear|init)s.*)\(void *\*\) *0\)/$1(mpfr_ptr) 0)/' **/*.c
under zsh.
