PR c++/78039 - fails to compile glibc tests

gcc/cp/ChangeLog:
        * class.c (diagnose_flexarrays): Avoid rejecting an invalid flexible
        array member with a hard error when it is followed by another member
        in a different struct, and instead issue just a pedantic warning.

gcc/testsuite/ChangeLog:
        * g++.dg/ext/flexary18.C: New test.
        * g++.dg/ext/flexary19.C: New test.

Added:
