I think, if remember correctly, that there is a behaviour change between
libtool 1.4 and 1.5 series for the Tru64 compiler.

With Tru64 cc compiler, shared objects can also be used to make a
static library. This mecanism is used in libtool 1.4 series to handle
both shared and static libraries. But, this exception was removed for
libtool 1.5 which now generates 2 separate objects (PIC vs. non PIC)
for the 2 libraries (shared vs. static); like other compilers.
