#Replace include of "projects.h" with "proj_api.h" and remove use of what is
#now considered an internal structure (struct PJ). 

#Proj.4 has removed "projects.h" from the installation of that library, because
#much that's in it is considered private implementation details that should
#not have been exposed.  That many packages use those internals directly is
#considered a problem in those other packages, and a bug request in proj.4's
#bug tracker to reinstate projects.h as an installed file was closed with
#the status "wontfix".  Codes that use the public API of proj.4 are supposed
#to include "proj_api.h" and use the API calls, not direct access to internal
#data structures or functions that are not intended for use outside the
#library.
