I'll double check that it doesn't work with 1.3.5, then upgrade
libtool to the latest cvs version and check again.
First for 1.3.5 thus:

which executes:

-fno-exceptions -pipe -Wall -Woverloaded-virtual -Wundef -Wpointer-arith -Winline

-fPIC -DPIC -o type_info.lo
That seems correct.

I am afraid that -liberty got linked in:
~/c++/libcw-objdir/.libs>nm libcwd.so.0.99.4 | grep xmalloc
00036a30 T xmalloc
00036a20 T xmalloc_set_program_name
while libiberty.a is a static library, not compiled with -fPIC.
This is bad. For the rest it looks conceptually like your line.

This is equivalent with the above

Duh. Well, you said that it was supported in 1.4, not 1.3.5.

Surely you mean: libtool c++ -Wall -O2 -g -o mytest mytest.o libcw.la
Note the libcwd.la -> libcw.la

Thanks, I'll follow up with the results under 1.4-to-be tomorrow.
