Richard,

I think this problem is that you need to install some special additional
C++ package.  It used to be part of the gcc package but sometime in the last
year it was split into a seperate package that requires a seperate install
step.  Norman Vine turned me on to this a month or two ago.  Check in your
Cygwin setup compiler package list for something c++ish.

There aren't any guidelines.  GDAL will install stuff into some or all of the
following:

  prefix/bin
  prefix/shared/gdal
  prefix/lib
  prefix/include
  prefix/man
  prefix/doc

Or even more places if you get the python stuff working.  For the purposes of
use with GRASS I think you could skip the python stuff, and it is the trickiest
stuff to get working on Cygwin.

Best regards,
