-f repo still not work in 2.95.2

Example is attached:


 According for info documentation, after relinking of x1.cpp and x2.cpp
we can create library with all needed template instantiations.

 on practice we have:

g++295 -I. -frepo -c x1.cpp
g++295 -I. -frepo -c x2.cpp
g++295 -I. -frepo x1.o x2.o | cat /dev/null

 relinking step must be failed

 This is error.,
