Comment (by strk):

 pramsey: it looks like you're right, this is a consequence of PGXS driving
 the flags !
 Today for example, on a new system, I have different flags:
 {{{
 gcc "-I../../liblwgeom"  -fPIC -I/usr/local/include
 -I/usr/include/libxml2     -I/usr/local/include "-I../../libpgcommon"
 -I../rt_core -I. -I./ -I/usr/include/postgresql/9.6/server
 -I/usr/include/postgresql/internal -Wdate-time -D_FORTIFY_SOURCE=2
 -D_GNU_SOURCE -I/usr/include/libxml2  -I/usr/include/tcl8.6  -c -o
 rtpg_create.o rtpg_create.c
 }}}

 I'm not sure what we want to do about this, if anything.
 Should we extract PGXS flags once from ./configure and use ours always?
