+Subject: [PATCH] include math.h to use predefined _Float128 definition
+
+glibc has added this patch [1] which defines __HAVE_FLOAT128 for clang
+therefore include math.h to avoid defining _Float128 during configure if
+not needed.
+
+Fixes
+cannot combine with previous '__float128' declaration specifier
