EXTERN doesn't work as -u

[Marcus Brinkmann]

Hi,

EXTERN doesn't seem to work properly.  I am using:

ulysses:/tmp# ld --version
GNU ld version 2.11.93.0.2 20020207 Debian/GNU Linux

The attached Makefile produces the following output:

ulysses:/tmp# make
echo 'main() {};' > foo.c
cc    -c -o foo.o foo.c
echo 'bar() { return 0; }' > bar.c
cc    -c -o bar.o bar.c
ar cru libbar.a bar.o
ranlib libbar.a
gcc -static -o foo1 foo.o -u bar libbar.a
echo 'EXTERN(bar);' > libbar-script.a
gcc -static -o foo2 foo.o libbar-script.a libbar.a
objdump --syms foo1 | grep bar && echo BAR defined in foo1 || echo BAR 
undefined in foo1
00000000 l    df *ABS*  00000000 bar.c
080481d0 g     F .text  00000009 bar
BAR defined in foo1
objdump --syms foo2 | grep bar && echo BAR defined in foo2 || echo BAR 
undefined in foo2
BAR undefined in foo2

I would expect that foo2 also contains the symbol bar.

The verbose runs were not really illuminative.  Here is the diff, except for
the command line itself:

I run ld in the debugger, and ldlang_add_undef was invoked for foo2, but I
don't know enough about the internals to see why it didn't have an effect.

Thanks,
Marcus

Thanks,
Marcus
