A differential 'MAKEALL arm' (ELDK42) show a sharp rise in board not 
building properly, from 74 to 141 (out of a total of 248).

Of the 67 boards, many show , essentially due to a lot of printf format 
warnings such as:

ks8695eth.c: In function 'ks8695_eth_send':
ks8695eth.c:199: warning: format '%x' expects type 'unsigned int', but 
argument 4 has type 'volatile void *'

(in cm4008, cm41xx), or

lcd.c: In function 'lcd_setmem':
lcd.c:446: warning: format '%d' expects type 'int', but argument 2 has 
type 'u_long'
lcd.c:446: warning: format '%d' expects type 'int', but argument 3 has 
type 'u_long'

(in at91sam9261ek_nandflash). Another, different, case is smdk2410:

s3c2410_nand.c: In function 's3c2410_hwcontrol':
s3c2410_nand.c:59: error: 'DEBUG' undeclared (first use in this function)
s3c2410_nand.c:59: error: (Each undeclared identifier is reported only once
s3c2410_nand.c:59: error: for each function it appears in.)
s3c2410_nand.c: In function 's3c2410_dev_ready':
s3c2410_nand.c:86: error: 'DEBUG' undeclared (first use in this function)
s3c2410_nand.c: In function 'board_nand_init':

Seems like you're trading some warnings against some others, depending 
on the compiler. :(

Amicalement,
