I have problems using dynamic libraries with version numbers.
Here is a small exeample with a dynamic library "library"
version 1.0 and a program "exe" which tries to use it:
	% g++ -fpic  -c exe.cc
	% g++ -fpic  -c library.cc
	% g++ -shared -o liblibrary.so.1.0 library.o
	% ln -s liblibrary.so.1.0 liblibrary.so
	% g++ -o exe exe.o -L/home/papadopo/TOTO -llibrary
	% 

The problem is that "exe" is linked against "liblibrary.so"
instead of "liblibrary.so.1.0":
	% ldd exe
	        liblibrary.so =>         ./liblibrary.so
	[...]
	% 

This was not the case with egcs-1.0.2:
	% ldd exe
	        liblibrary.so.1.0 =>     ./liblibrary.so.1.0
	[...]
	% 

The program won't run unless "liblibrary.so" is in the
LD_LIBRARY_PATH. "liblibrary.so.1.0" won't do.

Is this a bug? Am I missing something?
