 -shared        generate shared library
 

It compiles to 32-bit but fails for 64-bit, maybe due to compiled libphobos2
(64-bit) without -fPIC argument?

Another thing.
$ dmd -fPIC -shared foo.d -m32 -offoo.so.0.0.1
generate the incorrect "foo.so.0.0.so" file name.

but with:
$ dmd -fPIC -shared foo.d -m32 -L-ofoo.so.0.0.1
the correct "foo.so.0.0.1" file name is created.

You might have to wait a while for that. AFAIK there are no plans
currently to make phobos available as a shared library yet.

I personally think that phobos *should* be a shared object at some
point, but not everyone agrees with me.

I think that phobos should be a shared object too, but only when it has some
sense (by now, every dmd release breaks previous libraries, at least gtkd ones)

I suppose D/Phobos is currently still too volatile to start committing
to shared library version numbers yet. One *could* in theory start doing
it and just end up with very large version numbers, which the system in
theory can handle just fine, although people seem aversive to the
possibility of having /usr/lib/libphobos.so.2.x for all x from 0 to some
very large number.

ldc build already phobos / druntime as shared lib with

Well, i am able to build the GtkD shared libs for ldc2 with the current 
make file.

Not sure why ldc has it's own soname flag as only the linker would care 
about it so using -L to pass it on to the linker works just fine.
