	=== THIS IS NOT A BUG IN A SOURCE ===

... but I ran into a serious bug in the HP9000 C-compiler on HP9000/320
running HP-UX 5.3 when I tried to get perl 2.0 running.

It seems that this version of the C-compiler does not handle the following
construct correctly:

	(double) (d_var1 rel-op d_var2)

whre rel-op is one of ==, !=, <, >, <= or >= .

Either compiler errors or stack corruption can occur.

I posted a more explanative article in comp.sys.hp, and sent perl 
modifications to Larry Wall.
