And the build failure clearly connects to fenv: In file included from ../../../libquadmath/math/x2y2m1q.c:19: ../../../libquadmath/quadmath-imp.h:310:8: error: redefinition of 'struct rm_ctx' 310 | struct rm_ctx | ^~~~~~ In file included from ../../../libquadmath/quadmath-imp.h:32: /home/autobuild/autobuild/instance-16/output-1/host/i686-buildroot-linux-uclibc/sysroot/usr/include/fenv.h:137:8: note: originally defined here 137 | struct rm_ctx | ^~~~~~ Could you have a look into this?
