+/* Bypass sysdeps/posix/dl-fileid.h, which relies on st_dev/st_ino being
+   reliable.  Under NaCl, we cannot always expect them to be useful.
+   Fortunately, in the ways NaCl is used it's far less likely that two
+   different names for the same file would be used in dlopen or the like,
+   so failing to notice re-opening the same file is not so likely to be a
+   problem in practice.  */
