+/* printf is convenient because it allows various types to be printed in one
+ fairly compact call, so having gmp_printf support the standard types as
+ well as the gmp ones is important. This ends up meaning all the standard
+ parsing must be duplicated, to get a new routine recognising the gmp
+ extras.
+
+ With the currently favoured handling of mpz etc as Z, Q and F type
+ markers, it's not possible to use glibc register_printf_function since
+ that only accepts new conversion characters, not new types. If Z was a
+ conversion there'd be no way to specify hex, decimal or octal, or
+ similarly with F no way to specify fixed point or scientific format.
+
+ It seems wisest to pass conversions %f, %e and %g of float, double and
+ long double over to the standard printf. It'd be hard to be sure of
+ getting the right handling for NaNs, rounding, etc. Integer conversions
+ %d etc and string conversions %s on the other hand could be easily enough
+ handled within gmp_doprnt, but if floats are going to libc then it's just
+ as easy to send all non-gmp types there.
+
+ "Z" was a type marker for size_t in old glibc, but there seems no need to
+ provide access to that now "z" is standard.
+
+ In GMP 4.1.1 we documented "ll" and "L" as being equivalent, but in C99
+ in fact "ll" is just for long long and "L" just for long double.
+ Apparently GLIBC allows "L" for long long though. This doesn't affect
+ us as such, since both are passed through to the C library. To be
+ consistent with what we said before, the two are treated equivalently
+ here, and it's left to the C library to do what it thinks with them.
+
+ Possibilities:
+
+ "b" might be nice for binary output, and could even be supported for the
+ standard C types too if desired.
+
+ POSIX style "%n$" parameter numbering would be possible, but would need
+ to be handled completely within gmp_doprnt, since the numbering will be
+ all different once the format string it cut into pieces.
+
+ Some options for mpq formatting would be good. Perhaps a non-zero
+ precision field could give a width for the denominator and mean always
+ put a "/". A form "n+p/q" might interesting too, though perhaps that's
+ better left to applications.
+
+ Right now there's no way for an application to know whether types like
+ intmax_t are supported here. If configure is doing its job and the same
+ compiler is used for gmp as for the application then there shouldn't be
+ any problem, but perhaps gmp.h should have some preprocessor symbols to
+ say what libgmp can do. */
