that may be, but if that is what the gcc maintainer has decided, then 
complaining about it wont fix code like u-boot.  after all, u-boot hasnt told 
gcc that it wants strict preprocessor behavior (i.e. using something like -
ansi).  if it did, then gcc wouldnt have output any non-prefixed defines.
