I have tried to build a binutils for target cygwin by both native build under
Windows XP and cross build under Ubuntu 8.04. The problem is if the yacc parser
is not installed, the build of LD will fail because the ld/deffilep.y file can
not be parsed.
This takes me time to find out the problem bec

When linking a program with -Wl,--export-dynamic, no symbols are
exported. The problem arises when the executable needs to either dlopen
itself, or when it has plugins which are "linked" against it. Both

On Linux, to reproduce it, you may try

--defined-only ./addr2line |head -1 | awk '{print $1}'`
