--- Comment #6 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-09-21 14:00:03 UTC ---
The recompilation of lto-symtab.o during 'make install', but not the -Werror
related build failure, can be reproduced on x86_64-apple-darwin12 with...
% setenv CC clang
% setenv CXX clang++
% ../gcc-4.8-20120920/configure --prefix=/Users/howarth/dist
--enable-languages=c,c++,lto --with-gmp=/sw --with-libiconv-prefix=/sw
--with-isl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib
--enable-checking=yes --x-includes=/usr/X11R6/include
--x-libraries=/usr/X11R6/lib --disable-bootstrap
% make
% make install
where lto-symtab.o is recompiled starting with the r191466 commit. I assume
that nothing should be recompiled during 'make install' since that appears to
use the system compiler set with the CC/CXX environmentals and not the newly
built compiler.
