See my previous mail, actually this:
-TARGET_CPPFLAGS = @TARGET_CPPFLAGS@ -isystem=$(srcdir)/include
-I$(srcdir)/include -I$(builddir) -I$(builddir)/include \
+TARGET_CPPFLAGS = @TARGET_CPPFLAGS@ -nostdinc -isystem $(shell $(CC)
-print-file-name=include) -I$(srcdir)/include -I$(builddir)
-I$(builddir)/include \
The = in -isystem doestn't make much sense to me.
And with above -nostdinc really works for us.
