All the library-building is controlled by libtool and I'd really like

to keep it that way.  If there is an easy and clean way to do what you

want with libtool, I certainly would be willing to consider it.  You

may be best off compiling libunwind yourself, since you seem to have

special requirements.  Perhaps all you need to do is configure

libunwind with CFLAGS="-g -O2 -fPIC" and you'd be all set?

Doing a second clean build using those CFLAGS plus the --libdir switch to 
install the PIC versions in a separate lib directory should do it. Thanks,
