comparison is always true due to limited range of data type

[rahulOCR]

In SiK/Firmware/Radio/parameter.c ,

// Place the start away from the other params to allow for expantion 2<<7 +128 = 384
#ifdef INCLUDE_AES
// Holds the encrpytion string
__xdata uint8_t encryption_key[32];

#define PARAM_E_FLASH_START   (2<<7) + 128
#define PARAM_E_FLASH_END     (PARAM_E_FLASH_START + sizeof(encryption_key) + 3)

// Check to make sure the End of the pins and the beginning of encryption dont overlap
typedef char p2eCheck[(PIN_FLASH_END < PARAM_E_FLASH_START) ? 0 : -1]; 

In the check comparison is always True due to limited range of data type is coming. I have tried to fix it but unable because of compiler. Anybody that successfully compiled this please let me know the compiler version and any other fix for this issue.
