I don't run servers much, I mainly write for critical applications (a decade writing for geophysical airframes, telling pilots where to go and where the pylons are when 80m off the deck for millions of line kilometres, lot's of other stuff going back a long way).

As I said above .. there's no need for glibc et al.

We seem to be in agreement here.

What most people call "C" is (preprocessor) + (actual language) + (stdc function library).

What I call C (and hey, maybe that's just me) is just the language component, the "below the fold" library spec in the ANSI Std is easily disregarded .. it's more of a dated "proof of concept" of (for example) one of many ways of handling strings.

C is a nice language - the preprocessor and stdlib have issues.
