With the patch applied, I get:
checking for DWARF2 unwind info support... static
checking for __builtin_expect... yes
I guess that I configured GCC 3.1 wrong. gcc/auto-host.h has:
/* Define if your linker supports --eh-frame-hdr option. */
/* #undef HAVE_LD_EH_FRAME_HDR */
But I think I got it - GCC used the wrong assembler, I configured GCC
with --with-gnu-as and it used for detection /usr/bin/as - but for
building it used the newer binutils that were in /opt/binutils/bin.
Replacing my binutils in /usr/bin fixed the problems I had.
So, I'm happy for now - but I'll play a bit more around,
Andreas
