Hello,
I downloaded emacs-23.1 and tried to compile it for ARM,

gcc version 4.4.3 (Debian 4.4.3-1)
In my gcc-4.3.2 for Debian/ARM this symbol is both in the
'libgcc_s.so.1' and 'libgcc_eh.a' :
[root@Dell 4.3.2]# /usr/local/arm-debian-linux-gnueabi/bin/nm
libgcc_s.so.1 | grep __aeabi_unwind_cpp_pr0
000088fc T __aeabi_unwind_cpp_pr0
[root@Dell 4.3.2]# /usr/local/arm-debian-linux-gnueabi/bin/nm
libgcc_eh.a | grep __aeabi_unwind_cpp_pr0
00000494 T __aeabi_unwind_cpp_pr0
U __aeabi_unwind_cpp_pr0
U __aeabi_unwind_cpp_pr0
U __aeabi_unwind_cpp_pr0
and the 'libgcc' spec says :
*libgcc:
%{static|static-libgcc:-lgcc
-lgcc_eh}%{!static:%{!static-libgcc:%{!shared-libgcc:-lgcc --as-needed
-lgcc_s --no-as-needed}%{shared-libgcc:-lgcc_s%{!shared: -lgcc}}}}
So the '-lm -lgcc -lc -lgcc ' with the earlier 'gcc -nostdlib' in the
link command is something unexpected....
Does the emacs Makefile generate this kind of unexpected link command?
