Sorry I missed your mail.

Therefore it is:
RFC: Using DW_EH_PE_sdata* when converting absolute encodings to PC-relative
form
http://sourceware.org/ml/binutils/2009-09/msg00490.html

I do not agree (c) is a bug, according to previous GDB discussions it is
correct behavior:

http://sourceware.org/ml/gdb-patches/2010-02/msg00287.html
But as I see now fixing few GDB places to always sign-extend the displacement
CORE_ADDR will permit using the current standard 64bit math operators even for
32bit inferiors.

So this is not a GDB bug, the issue is already fixed in very old binutils.

If you need GDB compatibility with such old binaries/systems I find more
suitable a vendor/downstream patch in GDB port there.
