Replying to [comment:26 leif]:
> If `-foo` is mandatory to not break the build, it should be ''ap''pended
I don't think there are many situations where it's known that a flag is
absolutely required to not break the build. I like the principle of "the
user knows best" and not "the Sage developers know best".
> This especially holds for `-g`
The `-g` option can be cancelled by `-g0`.
> If a user sets `SAGE_DEBUG=yes`, he will or should be aware of the
consequences
Sure, but exactly the same holds for `CFLAGS`.
> If someone really wants to do debugging without e.g. `-O0`, he'll
certainly be able to modify `spkg-install` for that purpose, which is
trivial.
So now we require users to '''modify a spkg''' to get the options they
want? Why make things hard which should be easy?
> Temporarily modifying `C*FLAGS` is more tedious
Why that? Changing `CFLAGS` is equally easy as changing `SAGE_DEBUG`.
> and less experienced users may have (more or less intentionally) some of
them set
Why do you think that? Are there any distributions which have `CFLAGS`
set in the environment by default?
