So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

Namely these defconfig files:
boards/sim/sim/sim/configs/mtdpart/defconfig
boards/sim/sim/sim/configs/mtdrwb/defconfig
boards/sim/sim/sim/configs/rpproxy/defconfig
boards/sim/sim/sim/configs/rpserver/defconfig
boards/sim/sim/sim/configs/tcpblaster/defconfig
Because the recent versions of macOS is 64-bit only and thus
incompatible with CONFIG_SIM_M32=y.
The following defconfig files are left intact as these configs
are important for them:
boards/sim/sim/sim/configs/loadable/defconfig
boards/sim/sim/sim/configs/module32/defconfig
Because:
* A raw binary doesn't make sense for sim, where ./nuttx is
a host OS executable.
* It breaks test builds on macOS, where native objcopy
is not available.
* The appropriate size of stack varies among archs.
E.g. for 64-bit sim, 2048 is way too small, especially when the task
happens to use host OS functionalities.
I plan to allow an arch provide its own default.
* I plan to use this to replace hardcoded "STACKSIZE = 2048" in APPDIR.
Adds -fno-strict-aliasing to ARCHOPTIMIZAITON definition for all sim Make.defs file. This is constistent with the setting used in the Make.defs file of all other architectures and should eliminate the build test warnings:
arp/arp_arpin.c: In function 'arp_arpin':
arp/arp_arpin.c:136:13: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_sipaddr, &dev->d_ipaddr);
^~~~~~~~~~~~~~~~~~~~
arp/arp_format.c: In function 'arp_format':
arp/arp_format.c:96:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_dipaddr, &ipaddr);
^~~~~~~~~~~~~~~~~~~~
And similar warnings from icmp/icmp_input.c, and tcp/tcp_send.c. -fno-strict-aliasing i required for a warning free build of NuttX code since there is use of punned pointers.

initial addition
To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
Historically, the loopback driver used the largest packet size of all enabled link layer protocols. This permitted packets to be forward via the loopbak device with no major loss of performance. However, in experimenting with configurations where no other link layer protocols were enabled, this means the loopback packet size was set to the smallest possible size, to the SLIP minimum of 296 bytes. This resulted in terrible loopback performance.
This commit adds an option to increase the loopback packet size with the option CONFIG_NET_LOOPBACK_PACKETSIZE.
The loopback driver packet buffer should be quite large. The larger the loopback packet buffer, the better will be TCP performance of the loopback transfers. The Linux loopback device historically used packet buffers of size 16Kb, but that was increased in recent Linux versions to 64Kb. Those sizes may be excessive for resource constrained MCUs, however.
The network still enforces the lower limit that is the maximum packet size of all enabled link layer protocols. But this new option permits the loopback packet size to be increased from that.
* net/Kconfig: Adds CONFIG_NET_LOOPBACK_PKTSIZE option
* include/nuttx/net/netconfig.h: Assures that the packet size that is used is at least as large as the largest packet size of other link layer protocols.
* drivers/net/loopback.c: Use that larger packet size.
* boards/sim/sim/sim/configs/tcploop/defconfig: Set the loopback packet size to 1500
