[Gretl-devel] use of getenv() in the gretl source code

Hi all, due to a recent discussion in the user list https://gretlml.univpm.it/hyperkitty/list/gretl-users@gretlml.univpm.it/t... Allin and I have begun coding a slight modification to the --robust option to ols that enables the usage of that option with "gappy" time series data. A few minutes ago, I pushed a commit to the git master branch that makes the new behaviour conditional on the existence of an environment variable named "HAC_ALLOW_MISSING". This is a technique we've been using quite often to test new things. In fact, maybe _too_ often. The combined powers of grep and sed allowed me to compile a list of all the environment variables that play a role of some kind; although some are perfectly legitimate (eg HOME, LANG), some are clearly there because of experiments we did in the past. I guess we ought to clean up at least some of them. Of course, Allin and I could see to this without bothering the community, but this may be a good opportunity for aspiring developers to take a peek at the source code and see what's in there, so ideas and contributions from the community are very welcome.
