Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]):
--v-- description start --v--
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99:
struct foo { int stuff; struct boo array[]; };
By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on.
--^-- description end --^--
Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb).

Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]):
--v-- description start --v--
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99:
struct foo { int stuff; struct boo array[]; };
By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on.
--^-- description end --^--
Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb).
All these instances of code were found with the help of the following Coccinelle script:
