Summary:	Does dynamic linking affect LGPL conditions?

It appears that DJGPP will get DLL type libraries at some point in
the (near?) future.  Great!  Am I right in assuming that it will be
eventually possible to put the C and C++ libraries in DLLs?

The LGPL, covering programs linked to libgpp.a, requires one to
distribute the program in linkable form, "so that the user can
modify the Library and then relink to produce a modified executable
containing the modified Library."

Provided it is feasible to put all GNU C++ lib code in a libgpp.dll
file plus maybe another dll with template instantiations etc,
linking with the library would occur at run time.  Modifying the
library and linking it against the program as described in the LGPL
would be as simple as generating a new libgpp.dll.  Does this mean
that it'd no longer be necessary to provide the program's object
files?

I'd think that for commercial purposes, many would be happier
distributing libgpp.dll (+ source) rather than mysecretprogram.o.
