Hi all, I'm trying to build the RC of 4.9 with the latest released binutils (2.24) linked in-tree (using the symlink-all-the-binutils-files-into the root of gcc build trick). However, during the second stage, binutils fails to compile due to errors of the form: ../bfd/bfd.h:304:75: error: right-hand operand of comma expression has no effect [-Werror=unused-value] #define bfd_set_section_userdata(bfd, ptr, val) (((ptr)->userdata = (val)),TRUE) I've seen various posts on the net about this issue but no obvious workable solution. I've tried setting CFLAGS, CXXFLAGS and the equivalent *_FOR_TARGET to include '-Wno-error' but to no avail. Can someone give me a gentle nudge in the right direction here please? Thanks in advance, Matt
