--- Comment #3 from Brecht Sanders <brechtsanders at users dot sourceforge.net> --- Strange, I'm using the same binutils to build GCC 10.2.0 and have no issues there. Configuring the GCC build with `LDFLAGS_FOR_TARGET="-s"` works around this issue for now, but only for win64. For the win32 build libgfortran fails with `libgfortran/generated/matmul_c8.c:126: undefined reference to 'LC5'`
