[Remind-Fans] Upgraded to Ubuntu 20.04, got remind 3.3, bunch of new warnings from remind for stuff that worked before

[Jonathan Kamens]

I just upgraded my workstation to ubuntu 20.04, which has version 3.3 of 
remind which is a newer version than what I had in Ubuntu 19.10 
(3.1.16), and there are a several new warnings and errors when I run 
`rem -q -h`:

/home/jik/closed/remind/holidays.rem(37): Can't compute trigger
/home/jik/closed/remind/holidays.rem(52): Can't compute trigger
/home/jik/closed/remind/holidays.rem(112): Warning: Function name 
`_NotNextToShabba...' truncated to `_NotNextToShabba'
/home/jik/closed/remind/gann.rem(92): Cannot specify DURATION without 
specifying AT
/home/jik/closed/remind/family_google.rem(538): Cannot specify DURATION 
without specifying AT
/home/jik/closed/remind/family_google.rem(764): Cannot specify DURATION 
without specifying AT

The last three "Cannot specify DURATION without specifying AT" is 
correct and my fault and I will fix it. The one before that I guess I 
can address simply by shortening the name of the function and all the 
references to it. But the first two I'm not sure what's going on at all. 
These are the lines they're talking about:

REM  Sun Apr  1 ++2     SATISFY [trigdate() < '2007/01/01'] MSG Daylight 
Savings Time - %"DST starts%" %b%
REM  Sun [_last(Oct)]   SATISFY [trigdate() < '2007/01/01'] MSG Daylight 
Savings Time - %"DST over%"%

Any insights on why these two lines are problematic?

Thanks,
