I have a build failure on NetBSD as the namespace pollution avoidance causes a direct hit with the system /usr/include/math.h ======================================================================= In file included from /usr/src/local/gcc/obj/gcc/include/emmintrin.h:31, from /usr/src/local/gcc/obj/x86_64-unknown-netbsd10.99/libstdc++-v3/include/ext/random:45, from /usr/src/local/gcc/libstdc++-v3/include/precompiled/extc++.h:65: /usr/src/local/gcc/obj/gcc/include/xmmintrin.h:75:15: error: conflicting declaration 'typedef float __float_u' 75 | typedef float __float_u __attribute__ ((__may_alias__, __aligned__ (1))); | ^~~~~~~~~ In file included from /usr/src/local/gcc/obj/x86_64-unknown-netbsd10.99/libstdc++-v3/include/cmath:47, from /usr/src/local/gcc/obj/x86_64-unknown-netbsd10.99/libstdc++-v3/include/x86_64-unknown-netbsd10.99/bits/stdc++.h:114, from /usr/src/local/gcc/libstdc++-v3/include/precompiled/extc++.h:32: /usr/src/local/gcc/obj/gcc/include-fixed/math.h:49:7: note: previous declaration as 'union __float_u' 49 | union __float_u { gcc/ChangeLog: PR target/115796 * config/i386/emmintrin.h (__float_u): Rename to ..
