Yes, I am aware of that.

I do not often use defined C/C++ keywords on my webpage, so this
problem is easily avoided by putting "#undef linux" (or whatever
keyword you need to write) somewhere in the file included. Simple.

And yes, other problems like having to use " instead of " in the
source file, but you are supposed to do that anyway, so I really do
not see it as a problem.

Speak for yourself; it does *exactly* what I need.

I have gcc 2.95.4 (how it relates to 3.0 I don't know, but it can't be
*that* far off) and that works like a charm.

Last time I checked, C is written using ascii characters; the same as
english text.

I agree that it might be a better solution for this task, but then I
had to learn yet another tool. M4 is not something I have an interest
in learning.

It works fine for me; it simplifies the making of my webpage, and htat
is really all that I ask. In addition I get some experience with make
and gcc, which I consider a plus.

Cheers, Stig
