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'.
