Just as an experiment to see what my installation of DJGPP 2.03
(GCC 2.95.3) would do, I tried, and got this output:

x.cpp: In function `int main(int, char **)':
x.cpp:11: `::numeric_limits' undeclared (first use here)
x.cpp:11: parse error before `char'
x.cpp:12: `::istreambuf_iterator' undeclared (first use here)

Is this what you are getting ?

more or less errors then above here?

Unfortunately, I am not familiar with 'std' stuff. I only compiled
this out of curiousity, like I said.  Maybe we'll both learn something
new.
