+            subsequently.  It prevents a crash at startup under X in
+            `IRIX64 6.5 6.5.17m' with c_dev 7.3.1.3m.  It causes no
+            trouble on the other ELF platforms I could test (Irix
+            6.5.15m, Solaris 8, Debian Potato x86, Debian Woody
+            SPARC); however, it's reported to cause crashes under
+            some version of GNU/Linux.  It's not yet clear what's
+            changed in that Irix version to cause the problem, or why
+            the fix sometimes fails under GNU/Linux.  There's
+            probably no good reason to have something Irix-specific
+            here, but this will have to do for now.  IRIX6_5 is the
+            most specific macro we have to test.  -- fx 2002-10-01  */
