3.4, recent CVS, alpha Linux, bad code generation with "warning: the address ... will always be `true'"

[James W. McKelvey]

This code compiles fine with the HP/Compaq cxx compiler, so I believe it is 
OK. The code does not execute properly on g++, and gets the warning:

the address of `const PatternMaster::Pattern 
   look(PatternMaster::LookAheadPattern)', will always be `true'
