As a workaround, if you edit the variable CFLAGS in `src/Makefile' only,
replacing `-gcoff' with just '-g', then it should build. That is what I
did but I configure with `--no-debug'. I noticed this bug several weeks
ago but without your other patch I still could not build this release,
thanks. I am using libc built from the CVS development source besides
gcc 4.62 and binutils 2.22 .
