It would be nice if Pike could present a compelling argument. His web
page states only:
Multiple inclusions are a bane of systems programming. It's
not rare to have files included five or more times to compile
a single C source file. The Unix /usr/include/sys stuff is
terrible this way.
Where's the horror here? Computers are fast. Pushing extra work on
programmers and creating an unnecessary portability issue is a high
cost. Reading a header file five or more times during compilation is
a low cost (and one which can be optimized away for ifdef-protected
headers; I'm told gcc does so).
