I do not believe this patch is correct or necessary. What is it trying
to fix, and if there's a problem here then why is there not a problem in
every other one of our flex outputs?
If there is a real problem --- presumably of the form "some QNX header
file pollutes the namespace with a definition of ECHO" --- then a more
appropriate fix would be
+ #ifdef __QNX__
+ /* Get rid of conflicting definition of ECHO from QNX's <something.h> */
+ #undef ECHO
+ #endif
so as not to tie ourselves to the exact definition of ECHO that flex is
currently using. However, I would first like to know where the conflict
is and why it doesn't break every other flex output in existence.
