While we intentionally set -std=gnu11 for building host tools, and have for quite some time, we never dropped -std=gnu99 from tools/Makefile. This resulted in passing -std=gnu11 ... -std=gnu99 when building, and gnu99 would win. This in turn would result now in warnings such as: tools/mkeficapsule.c:25:15: warning: redefinition of typedef 'u32' is a C11 feature [-Wtypedef-redefinition] typedef __u32 u32; ^ Signed-off-by: Tom Rini <trini@konsulko.com>

# We are using a recursive build, so we need to do a little thinking
|
|
# to get the ordering right.
|
|
#
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
# their own directory. If in some directory we have a dependency on
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
# after that we are sure that everything which is in that other dir
|
|
# is now up to date.
|
|
#
|
|
# The only cases where we need to modify files which have global
|
|
# effects are thus separated out and done before the recursive
|
|
# descending is started. They are now explicitly listed as the
|
|
# prepare rule.

|
|
#
|
