# We use several libpgport and backend modules verbatim, but since we need
# to compile with appropriate options to build a shared lib, we can't
# necessarily use the same object files built for libpgport and the backend.
# Instead, symlink the source files in here and build our own object files.
# For some libpgport modules, this only happens if configure decides
# the module is needed (see filter hack in OBJS, above).
