Trouble linking 32-bit and 64-bit objects

["Allmen, Michael-P57512" <Michael dot Allmen at gdc4s dot com>]

I am having problems with binutils.  I want to build binutils so it will
generate 32-bit or 64-bit objects/executables on Solaris 9.  I am using
gcc-3.4.3 which is configured to use Sun as/ld by default.  I have been
working mainly with 2.15.97 but have also tried 2.15.

If I configure binutils with the default target (sparc-sun-solaris2.9),
I can build 32-bit objects/executables using gcc (gcc
-B/path/to/binutils/bin source.c).  If I attempt a 64-bit compile (gcc
-m64 -B/path/to/binutils/bin source.c), I get errors about incompatible
libraries.

If I configure binutils as 64-bit (sparcv9-sun-solaris2.9), I have the
opposite problem, I can compile 64-bit code but get errors for 32-bit
code.  

When I compile using Sun as/ld, I can compile 32-bit or 64-bit with no
errors.

I have tried using
--enable-targets=sparcv9-sun-solaris2.9,sparc-sun-solaris2.9 as
suggested in binutils/README with no success.  I have also tried
--enable-64-bit-bfd --enable-targets=all with no success.

Can GNU-binutils be built to generate 32-bit or 64-bit
objects/executables using the same binaries on Solaris?
 

Thank you.
