-From c37c9d599b9aced92e182507bf223440bbc9a9f1 Mon Sep 17 00:00:00 2001

-Subject: [PATCH] Portability: clean up support for binary128 (a.k.a.
- float128).
-
-This fixes a configure failure with Clang and glibc 2.41:
- https://bugs.gentoo.org/949962
- https://sourceware.org/bugzilla/show_bug.cgi?id=32750
- https://sympa.inria.fr/sympa/arc/mpfr/2025-02/msg00025.html
- https://sympa.inria.fr/sympa/arc/mpfr/2025-03/msg00001.html
-
-The issue is the following: in its configure script, GNU MPFR first
-tests whether _Float128 is supported (without header inclusions);
-if it isn't, MPFR then tests whether __float128 is supported, and
-in such a case, it defines _Float128 as __float128 with
-
- AC_DEFINE([_Float128],[__float128],[__float128 fallback])
-
-As Clang supports __float128 but not _Float128 (at least on x86_64,
-up to version 19), this fallback is selected. But glibc 2.41 has a
-similar fallback, with a typedef:
-
- typedef __float128 _Float128;
-
-With the MPFR _Float128 macro defined as __float128, as soon as some
-header such as <stdio.h> is included, this yields
-
- typedef __float128 __float128;
-
-which is incorrect. This first occurs in the
-
- AC_MSG_CHECKING(for GMP_NUMB_BITS and sizeof(mp_limb_t) consistency)
- [...]
-
-configure test (in configure.ac), hence the failure of this test and
-the configure script.
-
-As an attempt to avoid such an issue with header inclusion, a solution
-should be to include the common headers in every configure test.
-
-But since _Float128 is a reserved identifier, we must avoid defining
-it as a macro (a typedef would also be incorrect). This is done here,
-by defining a mpfr_float128 macro instead. In the public mpfr.h header
-file, if the user has defined MPFR_WANT_FLOAT128: mpfr_float128 will
-be defined as _Float128 by default (thus this will not change the API),
-but if _Float128 is not supported, the user should define mpfr_float128
-as __float128 (or an equivalent type that is supported).
-
-* acinclude.m4: changed _Float128 to mpfr_float128 in AC_DEFINE.
-* configure.ac: updated a comment about _Float128.
-* doc/README.dev: update about MPFR_WANT_FLOAT128 and _Float128.
-* doc/mpfr.texi: in "Nomenclature and Types", added a paragraph about
- binary128 support and the mpfr_float128 macro; update concerning the
- functions related to binary128 (in particular, in the prototypes,
- changed _Float128 to mpfr_float128).
-* src/mpfr.h: under "#ifdef MPFR_WANT_FLOAT128", define mpfr_float128
- as _Float128 if not defined yet; in the prototypes, changed
- _Float128 to mpfr_float128.
-* src/get_float128.c, src/set_float128.c, tests/tset_float128.c:
- changed _Float128 to mpfr_float128; updated comments.
-* tests/tversion.c: for "float128 = yes", also output the actual type.
