C extension: <? and >? operators

Question

I observed that there was at some point a <? and >? operator in GCC. How can I use these under GCC 4.5? Have they been removed, and if so, when?

Offset block_count = (cpfs->geo.block_size - block_offset) <? count; cpfs.c:473: error: expected expression before ‘?’ token 

Answer 1

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 use std::min and std::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).
