--- Comment #7 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
So since I've produced a working Stage3 compiler in the build directory, './',
'./prev-gcc' should be the directory containing the Stage2 gcc build, and
it does in my case, with a config.log :


$ grep '^LDFLAGS=' prev-gcc/config.log
LDFLAGS='-static-libstdc++ -static-libgcc '

Now I think that this command should produce the output :


$ grep '^LDFLAGS=' prev-gcc/config.log
LDFLAGS='-static-libstdc++ -static-libgcc -lstdc++'

because we know that all the executables are produced with xg++  
given the '-nostdlib' option, and all C++ executables should be
linked against libstdc++ .

My question is simply why isn't the missing '-lstdc++' there ?

Next question: where is the code that is meant to be adding it somehow ?
