+ Create fixed-length intermediate records past "end" of DB
+ correctly.
+ Realloc bug when reading in fixed records.
+ all: First cut at port to Alpha (64-bit architecture) using
+ 4.4BSD basic integral types typedef's.
+ Cast allocation pointers to shut up old compilers.
+ Rework PORT directory into OS/machine directories.
+
+1.72 -> 1.73
+ btree: If enough duplicate records were inserted and then deleted
+ that internal pages had references to empty pages of the
+ duplicate keys, the search function ended up on the wrong
+ page.

+

+
+1.6 -> 1.7 07 Sep 1993
+ hash: Fixed big key overflow bugs.
+ test: Portability hacks, rewrite test script, Makefile.
