V2: derived types

Hi,

I need to have some DLL created with custom extensions and I am getting 
warnings when I do that by deriving a type from SHARED_LIB. I'm 
attaching a test case that reproduces the conditions under which the 
problem occurs. In summary, this is the library dependencies that I have:
lib.mydll depends on baselib.a, which depends on libm.so

baselib's Jamfile is like this:

project baselib ;
lib libm : : <name>m <link>shared ;
lib baselib : a.cpp ;

lib's Jamfile is like this:
import type ;
type.register MY_LIB : : SHARED_LIB : main ;
type.set-generated-target-suffix MY_LIB : : mydll ;

my-lib a : a.cpp /baselib ;
# this works ---> lib a: a.cpp /baselib ;

Am I doing this in the wrong way?

Best,

Andre Hentz
