debian/patches/any/submitted-static-fmod-fmodf.diff

+From: Adhemerval Zanella <adhemerval.zanella@linaro.org>
+Subject: [PATCH v3 2/7] math: Fix i386 and m68k fmod/fmodf on static build (BZ
+ 31488)
+Date: Tue,  2 Apr 2024 11:06:39 -0300
+Message-Id: <20240402140644.2172819-3-adhemerval.zanella@linaro.org>
+
+The commit 16439f419b removed the static fmod/fmodf on i386 and m68k
+with and empty w_fmod.c (required for the ABIs that uses the newly
+implementation).  This patch fixes by adding the required symbols on
+the arch-specific w_fmod{f}_compat.c implementation.
+
+To statically build fmod fails on some ABI (alpha, s390, sparc) because
+it does not export the ldexpf128, this is also fixed by this patch.
+
+Checked on i686-linux-gnu and with a build for m68k-linux-gnu with
+'make test t=math/test-{float,double}-modf-static build-math-static-tests=yes'.
