/*
* cc.h - Architecture environment, some compiler specific, some
* environment specific (probably should move env stuff
* to sys_arch.h.)
*
* Typedefs for the types used by lwip -
* u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t
*
* Compiler hints for packing lwip's structures -
* PACK_STRUCT_FIELD(x)
* PACK_STRUCT_STRUCT
* PACK_STRUCT_BEGIN
* PACK_STRUCT_END
*
* Platform specific diagnostic output -
* LWIP_PLATFORM_DIAG(x) - non-fatal, print a message.
* LWIP_PLATFORM_ASSERT(x) - fatal, print message and abandon execution.
* Portability defines for printf formatters:
* U16_F, S16_F, X16_F, U32_F, S32_F, X32_F, SZT_F
*
* "lightweight" synchronization mechanisms -
* SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable.
* SYS_ARCH_PROTECT(x) - enter protection mode.
* SYS_ARCH_UNPROTECT(x) - leave protection mode.
*
* If the compiler does not provide memset() this file must include a
* definition of it, or include a file which defines it.
*
* This file must either include a system-local <errno.h> which defines
* the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO
* to make lwip/arch.h define the codes which are used throughout.
