[U-Boot] In U-Boot-2013-01, __stringify is not working

[Balaji N]

In U-Boot-2013-01 version & P3041 board, __stringify is not working.
Enabled the DEBUG mode and got the output as:

*** Warning - bad CRC, using default environment

In file include/env_default.h,

the environment variable is defines as:

#ifdef DEFAULT_ENV_INSTANCE_EMBEDDED
env_t environment __PPCENV__ = {
        ENV_CRC,        /* CRC Sum */
#ifdef CONFIG_SYS_REDUNDAND_ENVIRONMENT
        1,              /* Flags: valid */
#endif
        {
#elif defined(DEFAULT_ENV_INSTANCE_STATIC)
static char default_environment[] = {
#else
const uchar default_environment[] = {
#endif
#ifdef  CONFIG_ENV_CALLBACK_LIST_DEFAULT
        ENV_CALLBACK_VAR "=" CONFIG_ENV_CALLBACK_LIST_DEFAULT "\0"
#endif
#ifdef  CONFIG_ENV_FLAGS_LIST_DEFAULT
        ENV_FLAGS_VAR "=" CONFIG_ENV_FLAGS_LIST_DEFAULT "\0"
#endif
#ifdef  CONFIG_BOOTARGS
        "bootargs="     CONFIG_BOOTARGS                 "\0"
#endif
#ifdef  CONFIG_BOOTCOMMAND
        "bootcmd="      CONFIG_BOOTCOMMAND              "\0"
#endif
#ifdef  CONFIG_RAMBOOTCOMMAND
        "ramboot="      CONFIG_RAMBOOTCOMMAND           "\0"
#endif
#ifdef  CONFIG_NFSBOOTCOMMAND
        "nfsboot="      CONFIG_NFSBOOTCOMMAND           "\0"
#endif
#if defined(CONFIG_BOOTDELAY) && (CONFIG_BOOTDELAY >= 0)
        "bootdelay="    __stringify(CONFIG_BOOTDELAY)   "\0"
#endif
#if defined(CONFIG_BAUDRATE) && (CONFIG_BAUDRATE >= 0)
        "baudrate="     __stringify(CONFIG_BAUDRATE)    "\0"
#endif

For first 3 environment variable, it is working fine. When it reaches the
environment variable
"bootdelay="    __stringify(CONFIG_BOOTDELAY)   "\0"

it gets corrupted.
