# The echo stuff last in the dep update shell magic is to prevent any compiler
# errors/warnings to cause an error code to get returned and thus stop the
# build

# This script checks for the presence of $(BUILDDIR)/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.
