	PR c/35751
	* c-decl.c (finish_decl): If extern or static var has variable
	size, set TREE_TYPE (decl) to error_mark_node.

	* decl.c (layout_var_decl): If extern or static var has variable
	size, set TREE_TYPE (decl) to error_mark_node.

	* gcc.dg/gomp/pr35751.c: New test.
	* g++.dg/gomp/pr35751.C: New test.
