Yes, thanks, that sounds right, so let's continue the conversation about
this problem at <14585 <at> debbugs.gnu.org>. I'll mark16825 as done, since
its bug is fixed now.
Peter Dyballa, can you please try the following suggestion for
Bug#14585? It's taken from <http://bugs.gnu.org/16825#29>. Thanks.

Please try changing this line in src/Makefile:
LD_SWITCH_SYSTEM_TEMACS= ... 690 ...
so that the 690 is something larger. This is a hexadecimal number that
is a multiple of (decimal) 56. Please try 6C8, 700, etc., until you
find a number that works, and let us know. After editing src/Makefile,
remove src/temacs and then type 'make'.
I don't use Mac OS X, by the way; I'm merely deriving this suggestion
from David Reitter's email
<http://lists.gnu.org/archive/html/emacs-devel/2013-05/msg00462.html>.

Building emacs 24.3 on powerpc-apple-darwin gives me the
following error:
--- snip ---
gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I/Volumes/UFS_exp2/exptools/expmake/build/gnuemacs2src/emacs-24.3/lib -I../src -I/Volumes/UFS_exp2/exptools/expmake/build/gnuemacs2src/emacs-24.3/src -I/opt/exp/gnu/include -g3 -O2 -MT careadlinkat.o -MD -MP -MF .deps/careadlinkat.Tpo -c -o careadlinkat.o careadlinkat.c
In file included from unistd.h:43,
from careadlinkat.h:24,
from careadlinkat.c:23:
/usr/include/unistd.h:240: error: conflicting types for `rpl_readlink'
unistd.h:1559: error: previous declaration of `rpl_readlink'
--- snip ---
Looking at the 2 definitions of readlink I see in /usr/include/unistd.h:
int readlink(const char *, char *, int);
and in emacs-24.3/lib/unistd.h
_GL_FUNCDECL_RPL (readlink, ssize_t,
(const char *file, char *buf, size_t bufsize)
_GL_ARG_NONNULL ((1, 2)));
So it seems the 3rd parameter is different. Also I wonder why we include
2 different unistd.h files in the first place.
Attached is the complete configure/compile log.
