# Optional cflags for kbuild 2.4, to prevent individual files or an entire
# directory including files from outside the kernel.  To control an individual
# file, use CFLAGS_foo.o += $(kbuild_2_4_nostdinc), to control an entire
# directory use EXTRA_CFLAGS += $(kbuild_2_4_nostdinc).  In kbuild 2.5 the
# default is to forbid includes from outside the kernel tree, you can use this
# variable in kbuild 2.4 to ensure that your code is clean before 2.5.  KAO.

# other kernel code should include user space headers, if you need
# 'kbuild_2_4_nostdinc :=' or -I/usr/include for kernel code and you are not UML
# then your code is broken!  KAO.
