Bug 2018

Under VxWorks (and probably also some other embedded OS's) it is normal that 
when the application is started, argc = 0 and argv* = 0, several parts of 
ACE/TAO/CIAO use argv[0] without checking for argc. argv[0] is then unitialized 
memory and results in a crash under VxWorks. All code using argv[0] should 
check argc and if zero, not use argv[0]. This means probably that a lot of 
usage messages should be updated to hardcode the application name. 

This also appears in the ACE library itself and the TAO core libraries, those 
have a higher priority to solve.

This should also be documented in the readme's and books.
