 Marco's repository upheld most of these goals - but did not quite make it all of the way. As of mid-2021, it still had many C-standard-non-compliance bugs; the test suite was quite lacking in coverage; some goals were simply discarded (like avoiding global/local-static constants) etc. The repository had become quite popular, but unfortunately, Marco had been otherwise preoccupied; he had not really touched the code in the two years prior; many bug reports were pending, and so were many pull requests from eary adopters who had fixed some of the bugs they had encountered.
 
-The author of this fork was one of the latercomer bug-reporters-and-PR-authors; and when noticing nothing was moving forward, decided to take up the same goals (sans the discarded ones); and integrate the existing forks and available PRs into a single "consensus fork" which would continue where Marco had left off. Along the way, numerous other issues were observed; the build system was improved; the test suite streamlined and expanded; and other contributors also lent a hand (especially [@mickjc750](https://github.com/mickjc750/)). We are now very close to fully realizing the project goals.

-Note that `printf()` and `vprintf()`  don't actually write anything on their own: In addition to their parameters, you must provide them with a lower-level `putchar_()` function which they can call for actual printing. This is part of this library's independence: It is isolated from dealing with console/serial output, files etc.
