Message-ID: <200008011707.NAA25570@cse.psu.edu> (raw)
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).
While it may be simpler when it works, when
it fails it does so in mysterious ways. I don't know
how many times I've tried to figure out why
some header file I wanted wasn't getting included,
only to find that it had _already_ been included,
by someone else, with different things #defined,
so the definition or prototype_I_ wanted wasn't
there.
I'd much rather have the compiler barf on a
#define or something like that, than hop over
the whole file as though it weren't there.
