#3604: pgcommon/Makefile.in orders CFLAGS incorrectly leading to wrong liblwgeom.h
---------------------+---------------------------
 Reporter:  gdt      |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  medium   |  Milestone:  PostGIS 2.3.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 In both libpgcommon and postgis, CFLAGS end up with -I of system libraries
 before -I../liblwgeom.   This causes the installed version of liblwgeom.h
 to be picked up, instead of the version from the postgis sources,
 resulting in a build failure.

 I have observed the problem on NetBSD 6, and it has also been reported on
 FreeBSD: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211203

 The workaround is to remove the installed version.

 To fix, adjust CFLAGS/CPPFLAGS so that -I../liblwgeom is before includes
 of any directory that might have an installed version of postgis (e.g.
 -I/usr/pkg/include on NetBSD).
