Do you mean converting a C flexible array member (declared as
"foo[]") into a gcc zero-length array (declared as "foo[0]") ?
That seems like it would be going backwards from the direction
we started in with commits f7795e4096d8bd1c and 880a7817c1a82
of preferring flexible arrays to the GNU extension, so it's
maybe not ideal, but I guess it's expedient.
