The attached changeset [ce896fa7fd65] is an alternative implementation. It passes -DLEMON_ENABLE_DEBUG to the compiler instead of hard-wiring it in lemon/config.h. The difference is that if LEMON is built in debug mode, then [dd57dfa12bd5] will also set LEMON_ENABLE_DEBUG in external codes using LEMON, while [ce896fa7fd65] will not.
Always using -DLEMON_ENABLE_DEBUG helps revealing bugs, but may also slow down the execution in DEBUG mode too much. Note that -DLEMON_ENABLE_DEBUG may do extensive consistency checks, and will probably do even more in the future, see #462, #466
All in all, the question is --- which solution do you prefer?

I would prefer [ce896fa7fd65]. Users can still define LEMON_ENABLE_DEBUG, when they compile external code.

Yes they can. What I'm a bit uncertain whether they will actually do.
An alternative solution would be if Debug modes turned on LEMON_ENABLE_DEBUG, but the user could switch is off if it slows the execution down too much.

[ce896fa7fd65] has been merged into the main branch.
In fact a little bit modified version of it: [ee96cd1cad8a]
The attached changeset [dd57dfa12bd5] implements this by adding
to
lemon/config.hinDebugandMaintainerbuild types. The drawback of this solution is thatLEMON_ENABLE_DEBUGwill always be turned on in these modes. Which may or may not be desired.What is your opinion?
The alternative solution would be to pass
-DLEMON_ENABLE_DEBUGas a compilation flag when the test and demo codes are compiled.By the way
LEMON_ENABLE_DEBUGseems to reveal a bug in test/min_cost_flow_test.cc, see #478
