(__tzfile_compute): Likewise. Fix for PR libc/863. * timezone/Makefile: Generate GB timezone data for test. * timezone/tst-timezone.c: More tests for DST switching time (disabled for now). 1998-11-13 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/gnu/bits/utmp.h: Rename pad member of struct utmp to
