+# On some hosts (e.g., HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a
+# silly limit that it can create no more than 26 files from a given template.
+# Other systems lack mkstemp altogether.
+# On OSF1/Tru64 V4.0F, the system-provided mkstemp function can create
+# only 32 files per process.
+# On systems like the above, arrange to use the replacement function.
