  +First of all, is it really an error? If you find the option "-Werror" in the 
  +lines that calls gcc, the "error" you're facing could as well be a warning
  +(-Werror makes gcc handle all warnings as errors). You will often find warning 
  +and error messages mixed before the classical "make[1]: Error". A warning is 
  +something gcc complains about, but continues without error, while an error is 
  +something that stops you from compiling the package you are about to build.
  +To disable distracting warning messages, use "export CFLAGS="-w".

   Mostly further informations about the errors are missing, which is a nuisance
   for both the one who asks and the one who tries to answer, because of the
   annoying dialogue that is often following. I have to admid that the LFS mailing
