I should post this in the appropriate Gnu group, but we have be cut off from 
most of the news groups for the time being.

	unsigned u = 0;

	if (u-- < 4)
		printf("yes\n");
	else
		printf("no\n");

The Data General Aviion 5000 (an 88000 machine) version of GCC converts this 
into:

	unsigned u = 0;

	if(--u < 3) ....

for the assembly.

This obviously will produce counter-intuitive results.
