[Bug c/107951] Invalid flexible array use not detected in nested structs by the C frontend

--- Comment #6 from qinzhao at gcc dot gnu.org ---
after reading the history, my understanding is:

 this gcc extension is added as a workaround to build glibc since glibc source
code has such usage of flexible array members;

my question is: why not changing the glibc source code instead? then we don't
need such workaround in GCC?
