This is my first post to this newsgroup, however I've been reading it for a
while.

Could someone please tell me if this is just a quirk of the GNU iostreams
or if it is in fact "standard" behaviour.

When I compile and run the following program with gxx I get:

Sorry, can't open file.

However if I compile and run the program on the university's system using
either the Sun CC or the GNU g++ compilers, it works fine.

It seems that with the DJGPP version if the file does not exist and you
include the ios::in flag at all, it fails. (or am I missing something)

#include <iostream.h>
#include <fstream.h>

int main()
{
	fstream File;

	File.open("temp.txt", ios::in | ios::out);
	if(!File.good())
	{
		cerr << "Sorry, can't open file." << endl;
		return 1;
	}

	return 0;
}

BTW Many thanks to DJ Delorie and co. for a GREAT compilier suite.
