I still seem to be missing the point. Why ?

I presume you are talking about when you compile libc with the new
compiler, presumably using the new functions and therefore referring to 
the new libgcc_s.so. What would go wrong if I
did not bump the libc major ? It would be pulling in the new functions
with the new libgcc_s.so and the old functions from the old libgcc_s.so,
which would get shared with the old libgcc_s.so refered to by an old
program even if it loads the new libc, so everything would still be
unique, no ?
