(I note you're not the author of this)  I'm not exactly comfortable with 
making  FLEX a condition of being able to build GDB - while the above 
tries to hide it, the dependency still exists.  I guess we'll need to 
come back to that later.

Anyway, can you just re-post this patch with a separate ChangeLog and 
with the patch against CVS (using `cvs diff -u' or `cvs diff -p').
