A word of caution: be *very careful* doing this sort of thing, unless you
know exactly what you are doing. You can do this flatenning of the header
files for most packages, except for packages nc-dap, netcdf, netcdf4 and in
some cases hdf-4 (when netcdf is not disabled): all these packages implement
the netcdf API and have header files of the same name. Not only you have to
keep them apart,  but you also have to be careful not to include "netcdf.h"
from the netcdf package when building gradsdods, for example. The problem of
mixing and matching these header files is that the bugs can be very subtle:
everything builds and work 90% of time, and it can be extremely hard to
debug. For this reason, I reorganized the supplibs to keep all the header
files in separate directories for each package. It also makes it easier to
upgrade individual packages.
