Makefile

# Avoid -D_GLIBCXX_DEBUG for libraries; it changes the sizes of STL
# containers.  If main is built without it, trouble ensues.
# Code has to all use this feature, or none.

# Use of -Wall is mandatory EVERY time g++ executes.  You can’t just
# throw it into your Makefile.  It has to actually get USED each time.

# Put opts into the environment so that the echoed compile line just
# says “g++ $opts …” and it doesn’t list all the tedious options.
# However, -Wall DOES appear, so that we know it’s being used.
