Ah, I remember. There was a problem with stddef.h right?
So you propose something like this:
-TARGET_CPPFLAGS = @TARGET_CPPFLAGS@ -isystem=$(srcdir)/include
-I$(srcdir)/include -I$(builddir) -I$(builddir)/include \
+TARGET_CPPFLAGS = @TARGET_CPPFLAGS@ -isystem=$(shell $(CC)
-print-file-name=include) -I$(srcdir)/include -I$(builddir)
-I$(builddir)/include \
?

how) you may access your data; but nobody's threatening your freedom: we
still allow you to remove your data and not access it at all."
