Yes.  Adding -Winvalid-pch gives

cc1plus: warning: /home/rth/work/gcc/bld-head/alphaev67-unknown-linux-gnu/libstdc++-v3/include/alphaev67-unknown-linux-gnu/bits/stdc++.h.gch/O0g.gch: created and used with differing settings of '-mieee-conformant'

If I add -mieee to the command line (which is how libstdc++ itself is
built, but apparently not the testsuite), then I get

cc1plus: warning: /home/rth/work/gcc/bld-head/alphaev67-unknown-linux-gnu/libstdc++-v3/include/alphaev67-unknown-linux-gnu/bits/stdc++.h.gch/O0g.gch: not used because '__NO_INLINE__' not defined
