warning handling and allows for link-time warnings with a modified

completely when ldconfig unlinks it. If init is shared, then the
referenced unlinked copy of the hints file created by running
ldconfig in /etc/rc caused the file system to be unclean after
every reboot.
automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.

a few variable names have chaged (desc -> fd), and the formatting has

I tested 'make world' for /usr/src and X twice with these changes.
Paul Kranenburg's description:
ld is in error here, assuming that symbols with N_EXT set always have an
entry in the (global) symbol table: this is not the case for C++ generated
constructor/destructor symbols. I can reproduce your failure by fudging
a "multiply defined" constructor symbol by hand. Checking for `g == NULL'
seems to be a ok as a fence for now.
So:
for now, in do_file_warnings() we check if g == NULL, before trying to generate
any warning messages. This prevents a NULL pointer dereference.
to public. These functions are also used in /usr/include/link.h,
so it looks, like they shouldn't be private.
I will ask Paul about that, if this is correct.
late stage due to the fact that link.h was copyright Sun Microsystems.
This version of ld sync's us up with NetBSD's ld and supports compatablily
with NetBSD's -[zZ] flags (which we had reversed). Compiling with this
new ld will give you RRS warnings for libraries which do not contain .type
infomation - these wsarnings are harmless and will go away as soon as you
recompile your libraries (cd /usr/src; make libraries).
You write that
LDFLAGS+= -Xlinker -Bstatic
no more needed, but you have
CFLAGS += -static -I$(.CURDIR) -I$(.CURDIR)/$(MACHINE)
This -static doesn't make any sense in your version,
because it not passed to linker's state (LDFLAGS),
so we have SHARED /usr/bin/ld in this case.
(Older Makefile produce non-shared ld).
I suppose, that -static in CFLAGS was introduced to
make non-shared ld, so I restore previous LDFLAGS
to have non-shared ld. If we want to have shared ld
we need to remove -static from CFLAGS too, not only LDFLAGS,
but this need special issue and corresponding
commit log. Your current version hang into intermediate
state (beetween two sides), so I move it to one side.
Second, I restore NOPIC dependance again from older Makefile:
.if !defined(NOPIC)
SUBDIR+= rtld
.endif
We don't need ld.so, if NOPIC
P.S. I don't see any purpose to commit new makefile, old version
is better.
