db1 vs. db2

[James Antill <nevyn@and.org>]

 I've just upgraded from glibc-2.0.7-pre something to glibc-2.0.112
and noticed that there are now..

 db.h
 db1/db.h

 and...

 libdb
 libdb1

 Now compiling something that used to work against db.h/libdb now
fails with...

gcc -O  -o exim_dbmbuild  exim_dbmbuild.c \
  os.o -lnsl  -ldb1 -lwrap
/tmp/ccp3xvGN.o: In function `main':
/tmp/ccp3xvGN.o(.text+0x1ee): undefined reference to `db_open'
collect2: ld returned 1 exit status

 Changing the include <db.h> to include <db1/db.h> (or adding
-I/usr/include/db1) seems to fix the problem, but what I'm wondering
is what the libdb1 is for.
 The above program (exim-2.11 GPL'd) seems to work linked with either, 
but the sizes are very different and the libdb1 seems to have the same 
kinds of symbols that the 2.0.7 libdb had.
