Автор зачем-то приводит заголовок файла dbug.c из исходников пакета (вместе со всеми комментариями к нему). Приведу его и я, поскольку это может быть продиктовано какими-либо юридическими проблемами с копирайтом. Поскольку я не юрист, привожу этот заголовок без какого-либо перевода (во избежание ошибок или искажения смысла юридического документа при переводе).

 *      @(#)dbug.c      1.25    7/25/89
 *
 *  DESCRIPTION
 *      These are the runtime support routines for the dbug package.
 *      The dbug package has two main components; the user include
 *      file containing various macro definitions, and the runtime
 *      support routines which are called from the macro expansions.
 *
 *      Externally visible functions in the runtime support module
 *      use the naming convention pattern "_db_xx...xx_", thus
 *      they are unlikely to collide with user defined function names.

 *      Check of malloc on entry/exit (option "S")
