Recent manuals say:
The G++ minimum and maximum operators (‘
<?
’ and ‘>?
’) and their compound forms (‘<?=
’) and ‘>?=
’) have been deprecated and are now removed from G++. Code using these operators should be modified to usestd::min
andstd::max
instead.
A quick search of the past documents seems to indicate that they were removed around version 4.0 (3.4.6 includes them, 4.0.4 does not).
