+	Change identifier spellings to avoid collisions with names
+	that are reserved by POSIX.
+
+	Don't use names ending in _t, since POSIX reserves them.
+	For consistency, remove _e and _s endings -- they're weren't
+	needed to remove ambiguity.  All uses changed.

+
+	Reorder all include files under src to be in the order "system.h".

+	then the . include files in double-quotes (alphabetized).  Fix
+	dependency breakages encountered in this process, as follows:
+	* src/closure.h, src/derives.h, src/state.h: Include "gram.h".
+	* src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
