Please ignore this final change to maybe_trim_memstar_call, which I've now removed from the patch. Jason Merrill has now explained that these warnings are issues with the (RedHat) system compiler on my host system rather than code cleanliness issues with GCC source tree. I just need to ignore these compiler warnings in stage1 of a bootstrap/build, even in the source files I'm changing. Sorry for the noise. Hopefully the rest looks good. Cheers, Roger --
