Hello Andrew.  I can give it a try, but up against time constraints at the
moment. :(  This looks like a nice guide btw!  I've been a bit of a stranger on
gcc lately.

Also this project has a mix of C and C++ sources, the later built as follows:

g++ -DHAVE_CONFIG_H -O2 -march=native -g3 -flto -std=gnu++11 -Wall -Wextra
-Wno-unused-parameter -Wno-ignored-qualifiers -MT my_file.o -MD -MP -MF
.deps/my_file.Tpo -c -o my_file.o my_file.cc
