+	* configure.in (RUBY_NACL and others): merge patch from naclports. Supports PNaCl.
+	* dln.c: ditto. replace the old hacky dynamic loading over HTTP with nacl_io.
+	* file.c: ditto. tenatively use access(2) instead of eaccess.
+	  (rb_file_load_ok): weaken with attribute but not by postprocess.
+	* io.c: ditto.
+	  (socket.h): now NaCl has socket.h
+	  (flock): disable here instead of nacl/ioctl.h
+	* nacl/GNUmakefile.in: ditto.
+	  (CC, LD, NM, AR, AS, RANLIB, OBJDUMP, OBJCOPY):
+	  respect path to them if they are absolute.
+	  This helps naclports to build ruby in their source tree.

+	  (ruby.o, file.o): move the hack to attributes in ruby.c and file.c
+	* nacl/ioctl.h: ditto. removed. move the hack to io.c.
