# This script checks for the presence of $(BUILDDIR)/lang/lang.h and if it doesn't
|
|
# alreay exist, it is created. This is because lots of files include this
|
|
# *generated* file and if it doesn't exist when we generate the deps it is no
|
|
# good. There's a -MG compiler option to cover for this case, but it doesn't
|
|
# play nicely into this as it then adds a dependency to the lang.h file
|
|
# without the proper path.
|
|
#
|
|
# The trailing sed hack for a range of files is present because how gcc works
|
|
# for generating dependencies when the include file doesn't exist. Then it
|
|
# makes the dependency without any path, and that breaks how things work for
|
|
# us. We thus add the correct path for a few generated files!
