Binutils is pretty old:
ld -V
GNU ld version 2.16.1
Supported emulations:
elf_x86_64
elf_i386
i386nbsd
Configure command is:
/home/jwakely/src/gcc/configure --prefix=/home/jwakely/gcc/4.x
--with-system-zlib --with-gnu-ld --with-gnu-as --with-dwarf2
--enable-languages=c,c++ --disable-libquadmath --disable-libmudflap
--disable-libitm --disable-decimal-float --disable-nls
Note that I specifically requested --with-dwarf2, which makes no difference.
