fts_children needs to return user's logical hierarchy;
make fts_errno visible to the user and add FTS_INIT state

get rid of the savelink stuff and just add another pointer field
to the FTSENT structure

fts_dfd unused

put ssize_t in <sys/types.h>, as specified by POSIX

add optopt to the list of getopt(3) extenrs

pointers to pointers, not pointers

add inet_aton prototype

isascii, isblank and toascii aren't in ANSI

added netccitt

List definitions after function declarations, or Reiser cpp gets upset.

move the signal(3) prototype back into <sys/signal.h> to make the
applications happy

break sys/signal.h into user level and system level

add isblank(c)

port.h has typedef's for u_'s, do it right for BSD

minimize the dependencies on <sys/types.h

add prototype for dbm_dirfno; make dbm_pagfno fail on compile

minor rearrangements

bump the hash version to 2; (allocate overflow pages beyond EOF)

fold routine flags into one list; add pointer oriented swap macros;
make get routine key argument a const.

added pmax/mips changes

Rev #2; new interface, btrees, recno's.

add mpool.h

checkpoint btree mpool

fread/fwrite return size_t

DBT should have a size_t as an arg, not an int
