3490.0. "Why stream.h does not include fstream.h" by TKTV30::HASEGAWA () Thu Mar 13 1997 02:06
Our customer have a question about "stream.h and fstream.h".
On the former C++ version(V5.1), stream.h include "fstream.h",
but on the late version(V5.3) stream.h does not include "fstream.h".
They would like to know the reason why the change was done. C++ releasenotes
does not seem to describe the issue.
Does anyone know about this ?
Thanks in advance.

main() {
fstream file;
file.open("test",ios::in);
file.close(); }
% cxx test.cxx
cxx: Error: test.cxx, line 5: Missing ";".
fstream file;

fstream file;
file.open("test",ios::in);
file.close(); }

It appears it was done by a prior engineer on the project. The CMS history
for stream.h only shows it including <stream.hxx> and no mention of
fstream.h.
The current documentation on fstream lists fstream.h[xx] as the file to include
so I can only think that the reason it was removed is because it was
there in error to begin with.
