Hello, guys.

In post-gcc42 -CURRENT:

cc -shared -fPIC -o libmts.so mtest.c -lm -pthread
~~~~~~~ ~~~~~~~~
ldd ./libmts.so
./libmts.so:
libm.so.5 => /lib/libm.so.5 (0x800b01000)
libthr.so.3 => /lib/libthr.so.3 (0x800c1b000)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
libc.so.7 => /lib/libc.so.7 (0x800631000)

>From old gcc specs:

*lib:
%{!shared:
%{!pg: %{pthread:-lpthread} -lc}
%{pg: %{pthread:-lpthread_p} -lc_p}
}

Now:

*lib:
%{!shared:
%{!pg: %{pthread:-lpthread} -lc}
%{pg: %{pthread:-lpthread_p} -lc_p}
}
%{shared: %{pthread:-lpthread} -lc}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Is this behaviour intended?

Regards,
Vladimir
