+ INTERNAL:
+
+ - Did a code audit using IBM's code-checker program and made several
+ changes, including: replacing most of the strcpy() and sprintf()
+ calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
+ an enum that had been intermingling a literal 0 with the defined enum
+ values, silencing some uninitialized memory checks, marking some
+ functions with a "noreturn" attribute, and changing an "if" that
+ could never succeed on some platforms into a pre-processor directive
+ that conditionally compiles the code.
+
+ - Fixed a potential bug in f_name_cmp() when both the args are a
+ top-level "." dir (which doesn't happen in normal operations).
+
+ - Changed exit_cleanup() so that it can never return instead of exit.
+ The old code might return if it found the exit_cleanup() function
+ was being called recursively. The new code is segmented so that
+ any recursive calls move on to the next step of the exit-processing.
+
+ - The macro WIFEXITED(stat) will now be defined if the OS didn't already
+ define it.
