Did you build newlib along side GCC? Or did you do the two steps of building
GCC with C only and then newlib and then GCC with C++ support?

I tried newlib, newlib said it does not support pdp11-aout target anymore.

I suggest removing pdp11 target support if it is so buggy.

remove the entire backend from GCC.

--- Comment #5 from pkoning at gcc dot gnu.org ---
There is no pdp11 support in newlib (and never was as far as I know; it's not a
matter of it having been "removed").  I've played with creating one, but not
enough to submit the result.

But that doesn't make the pdp11 target meaningless or say it needs to be
removed.  The only consequence of the lack of an off the shelf library package
is that you can't run the execution testsuite.  But you can, for example, run
the compile part of the testsuite.
