Hello.
Sorry for such issue during Friday evening. The problem is that for target
compiler, target_option_default_node == NULL. I am not so familiar with options
if this is correct situation?
Anyway, following suggested patch return NULL as cl_target_option that compared
correctly:
diff --git a/gcc/tree.h b/gcc/tree.h
index e9af9bf..d3f13e8 100644
--- a/gcc/tree.h
+++ b/gcc/tree.h
@@ -4678,6 +4678,10 @@ target_opts_for_fn (const_tree fndecl)
tree fn_opts = DECL_FUNCTION_SPECIFIC_TARGET (fndecl);
if (fn_opts == NULL_TREE)
fn_opts = target_option_default_node;
+
+ if (fn_opts == NULL_TREE)
+ return NULL;
+
return TREE_TARGET_OPTION (fn_opts);
}

GNU diff can can merge two C/C++ header files with the proper ifdef-ery: see:
http://www.gnu.org/software/diffutils/manual/html_mono/diff.html#If-then-else
and also:
http://www.gnu.org/software/diffutils/manual/html_mono/diff.html#Detailed%20If-then-else
This could be done as part of the generation of the header at build time.
