 DEBUG and TLOG should be defined in the Makefile if you want debugging
 and transaction logs.  Don't define them if you want to save the space
 and overhead.  (Note, in version 4F these definitions changed from "{}"
 to the null string to avoid problems with semicolons after braces, as in:
 "if (x) tlog(this); else tlog(that);"
