-
- I'd bet that not a single successful commercial application has ever been
- written to Posix interfaces only. Most installed Unix platforms do not conform
- to Posix 1003.1, much less to the draft standards. (1003.1 is the system API,
- and is the only official standard so far.) You can work around much of this
- with configuration hacks but this means you're not using Posix interfaces only.
-
- Furthermore, 1003.1 does not cover areas crucial to most application software.
- Doug Gwyn pointed out the most glaring deficiency, namely user interfaces;
- but there are several others.
-
- Posix conformance is a worthy goal, but the best option for most real
- applications is to strive for ``conforming using extensions'', instead of
- ``strictly conforming'' or ``conforming'' as Moore seems to be asking for.
