      Now after installing flex and re-checkout it works.

      Now I wonder, this has to be a bug in the build logic, no?

      When I don't have flex installed, why doesn't the "loader.c"

      used to work, because I've never installed flex before.
     
     
  Taking a quick look and doing some tests on my system, it appears that when 
doing a cvs update, the datestamp on the file is that of current time, and not 
last change on the file.

  I would _think_ that the checkout would happen in alphabetical order, so that 
loader.c would get checked out before loader.l, and thus it should be newer. 
Perhaps the time were equivalant (not sure if the times in the inode are any 
finer resolution than the second), so make decided to update it.

  Note that you could have fixed the problem by just removing the loader.c and 
then do a cvs update - the one it pulled down should also have a newer time and 
thus be OK.

  The makefile could/should perhaps be smarter - it no flex is installed, don't 
try to rebuild the file.  And at least spit out an error message.
