  Far too much practice  :-)
  
  More serious answer: the link error messages indicated that the constructor
  for OsiVol was missing.  When something that basic is missing, it tends to
  indicate a missing library in the link command, and sure enough -lOsiVol and
  -lVol were absent. The leap from there to Makefile.location comes from having
  spent too much time adjusting the old Coin build system.

  Your timing on the initial post was pretty good, really, and the correct
  amount of information. COIN software should build without you having to take
  extreme measures or become an expert in software build systems. It's more
  confusing than usual just now because most core COIN software has converted to
  the standard GNU autotools system (configure) while some (such as MaxCut)
  still uses our old custom makefile system.

  If you're getting cygwin build errors, send 'em in and we'll have a look.
  Might be a few days to sort it out.
  
  (I'd be more definite, but I'm just minding the store for the folks who really
  know BCP. Something about being forced to go to Rio de Janeiro for some kind
  of conference.)
