(find_constant_wide): Cast find_constant2's integer arguments to
`jword'.

argument to push_long_const to HOST_WIDE_INT.
(This is a forgotten patch.)

* config/rs6000/eabi-ctors.c (__do_global_ctors): Run through
__CTOR_LIST__ in opposite order, which is the correct order for sorted
constructors.
(__do_global_dtors): similarly for __DTOR_LIST__.
From-SVN: r29925
* libU77/aclocal.m4: Re-write, defining LIBU77_GETTIMEOFDAY, not
LIBU77_HAVE_STRUCT_TIMEZONE.
* libU77/configure.in: Use LIBU77_GETTIMEOFDAY, not
LIBU77_HAVE_STRUCT_TIMEZONE. Don't check for gettimeofday
separately.
* libU77/datetime_.c (G77_date_and_time_0): Use
GETTIMEOFDAY_ONE_ARGUMENT.
From-SVN: r29917

POSTINCREMENT_EXPR rather than a naked 'int'.
From-SVN: r29898
