Update.

1999-06-14  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/sys/sysmacros.h [!__GNUC__]: Use correct
	word order.
	* sysdeps/unix/sysv/linux/alpha/sys/sysmacros.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sys/sysmacros.h: New file.

1999-06-15  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* db2/db/db.c: Restore __nss_db_open alias.
	* db2/db_int.h: Use <db.h> instead of "db.h" to find header in
	include.
	* db2/os/os_rw.c (__os_write): Maintain const correctness.
	* db2/progs/db_load/db_load.c (main): Avoid ambiguous `else'.
