For simplicty, in the preprocessed source, edit the Makefile, set
CXXFLAGS= -pipe -I. -Wall -fopenmp -march=native

Then,
gccbug39573$ make clean; make
rm -f *.o *~ shapes
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o mainpp.o mainpp.cc
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o tinystrpp.o tinystrpp.cc
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o tinyxmlpp.o tinyxmlpp.cc
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o tinyxmlerrorpp.o
tinyxmlerrorpp.cc
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o tinyxmlparserpp.o
tinyxmlparserpp.cc
gcc -pipe -I. -Wall -fopenmp -march=native   -c -o SurfaceExtractorpp.o
