shared libobjc, libstdc++

[nicola at brainstorm dot co dot uk]

Hi,
I am working on adding shared lib support in GNU Objective-C runtime
(libobjc).

It's only a configuration problem - involving editing the configure.in and
Makefile.in.  But I'd like to do it pretty well, so that it can be
contributed back to gcc.

I already did it with stand alone code, and it works nice, but I'd like it
to be as much integrated as possible with the other gcc parts.

To me it does not look like I can simply borrow libstdc++'s shared lib
support, or use or rely on the work already done on libstdc++ or in other
gcc libs - even if it would be really desiderable.

Anybody with some experience on these things (particularly with the
libstdc++ shared lib configuration stuff) can confirm my impression and/or
give me suggestions/hints on how to work things out to be as much
integrated with the rest as possible ?

Please note that it would be nice to have all the cross options: static
but no garbage collector, static with gc, shared without gc, shared with
gc.

Thanks for any suggestions.
