This patch breaks the build of libgfortran on darwin.
http://gcc.gnu.org/ml/gcc-cvs/2005-11/msg00601.html
-all_load ./.libs/libmatmul.a -lm ./.libs/libmatmul.a -lc
-Wl,-single_module -install_name
/Volumes/export/gcc/gcc-svn/head/testbin/lib/libgfortran.0.dylib
-compatibility_version 1 -current_version 1.0
ld: multiple definitions of symbol __gfortran_matmul_i4
./.libs/libmatmul.a(libmatmul_la-matmul_i4.o) definition of
__gfortran_matmul_i4 in section (__TEXT,__text)
./.libs/libmatmul.a(libmatmul_la-matmul_i4.o) definition of
__gfortran_matmul_i4 in section (__TEXT,__text)
The reason is that the link command tries to link two times the libmatmul.a
which gives the duplicates.
Atm, I have not a solution handy, but it seems to me that using convenience
library scheme would be the solution.
Modifying the libtool and removing the $convenience part in libtools
whole_archive_flag_spec makes it link and pass the testsuite.
Sorry for not posting a solution right now. Moving pressure :)

------- Comment #1 from jb at gcc dot gnu dot org 2005-11-16 23:00 -------
As discussed on IRC, the solution is to use noinst_LTLIBRARIES instead of
EXTRA_LTLIBRARIES. It was also suggested to name the library
libmatmul_convenience.a. Example in libffi/Makefile.am

Unfortunately it does not werk :(
I found this message in the libtool archive:
http://lists.gnu.org/archive/html/libtool-patches/2004-08/msg00002.html
Currently we have this 'whole_archive_flag_spec='-all_load $convenience''
in gcc-root/ltcf-c.sh (for darwin)
Is this needed somehwere?
Maybe we could remove this -all_load $convenience' entry in the ltcf-c.sh?
Geoff?
Doing so by hand in the gfortran libtool makes the library link.

It's certainly wrong to be using -all-load unless you're also using -r.

------- Comment #6 from andreast at gcc dot gnu dot org 2005-11-18 14:31 -------
On sparc-solaris I get runtime failures:
collect2: ld returned 1 exit status^M
compiler exited with status 1
output is:
Undefined first referenced^M
symbol in file^M
_gfortran_matmul_r4 /var/tmp//ccKKiCDj.o^M
ld: fatal: Symbol referencing errors. No output written to ./matmul_1.exe^M
collect2: ld returned 1 exit status^M
this is with both, the original libmatmul and with libmatmul_convenience.
(using native, sun, as and ld)
I try to investigate deeper by next week. If I do not get beaten by others :)

------- Comment #8 from jb at gcc dot gnu dot org 2005-11-20 21:39 -------
rth committed a fix to trunk and 4.1:
http://gcc.gnu.org/ml/fortran/2005-11/msg00548.html
It should now work again on all supported platforms.
Unless new problems are reported I'll close this in a few days.

With the fix by rth, it seems to work again on Solaris (#9) and Darwin (
http://gcc.gnu.org/ml/fortran/2005-11/msg00571.html ); closing the bug.
