This commit resolves issue #620: Remove CONFIG_CAN_PASS_STRUCTS #620 The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example: #ifdef CONFIG_CAN_PASS_STRUCTS struct mallinfo mallinfo(void); #else int mallinfo(FAR struct mallinfo *info); #endif And even leads to violation of a few POSIX interfaces like: #ifdef CONFIG_CAN_PASS_STRUCTS int sigqueue(int pid, int signo, union sigval value); #else int sigqueue(int pid, int signo, FAR void *sival_ptr); #endif This breaks the 1st INVIOLABLES rule: Strict POSIX compliance ----------------------- o Strict conformance to the portable standard OS interface as defined at OpenGroup.org. o A deeply embedded system requires some special support. Special support must be minimized. o The portable interface must never be compromised only for the sake of expediency. o Expediency or even improved performance are not justifications for violation of the strict POSIX interface Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132 NOTE: This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.
