OO build with symbols not stripped

Hi all,

I am trying to elaborate fix for
http://www.openoffice.org/issues/show_bug.cgi?id=63383 (callouts copy
icorrectly from Draw to Writer) but have some issues with OO build.
I'd like to build OO with symbols to be able to debug it with gdb, but
the symbols get stripped from .so libraries during build.
I'm on opensuse11.1 x86_64, I use

./configure --enable-debug --disable-mozilla --without-junit
--disable-odk --enable-symbols
./bootstrap
source LinuxX86-64Env.Set.sh
export PKGFORMAT=installed
cd instsetoo_native && build --all -P4 -- -P4

but nevertheless symbols are not available for gdb. Looking for SwWW in
instsetoo_native/unxlngx6.pro/OpenOffice/installed/install I find it
only libmswordlx.so, which must be product of sw module build,
unfortunately the library is stripped of symbols. What I am doing wrong,
how to say the build system to let the symbols stay?

Regards, Slava
