+    Linux defines NOFILE as 256.
+ 
+    I want to force the same or better behavior on AIX.
+    Otherwise NOFILE will be defined as "OPEN_MAX" and this will be depending

+    "EBADF" ("bad file descriptor") errors and thus will only slow down the
+    startup of tcsh.
+    In order to reduce the number of EBADF errors this will be defined as 32. */
