problem with -fPIC flag

If you create a library from object files (that are listed in the 
Jamfile explicitly), the -fPIC flag is not used when compiling a shared 
library (I'm using the gcc toolset)

I have attached a small test-case that shows the problem. My Jamfile 
looks like

<quote>
object bar_object : bar.cpp ;
lib libbar : bar_object ;

lib libfoo : foo.cpp ;
</quote>

When compiling the intermediate foo.o object-file, the -fPIC flag is 
used when creating a shared libfoo library. When creating a shared 
libbar library however, the -fPIC flag is not used when compiling the 
bar.o object file '-(

The solution I see is adding following to gcc.jam
<quote>
if [ os.name ] != CYGWIN && [ os.name ] != NT
{
flags gcc.compile OPTIONS <link>shared/<main-target-type>LIB : -fPIC ;
+ flags gcc.compile OPTIONS <link>shared/<main-target-type>OBJ : -fPIC ;
}
</quote>

Can anybody tell me if this is indeed the way to go?
