We have been using designer C++ on various machines (sun3, hp9000) for 
almost two years and have been relatively satisfied with the compilers.

Lately we install one on our sun4 ( release 1.2 Sun4-Wk.2d (beta 1 FOR
SOME REASON !!)).  Then a really nasty thing turned out - ostreams which
open a file do not work.  The symptoms are:

	int fd = open (xxxxxx)
	// file really gets opened/created
	ostream* aStrm = new ostream(fd) ;
		// this line generates two warnings to stderr, "illegal
		// pointer combination", they come from the inline 
		// constructors of filebuf and streambuf
	*aStrm << "Write something \n" ;
	close (fd) ;

Only 377 is written to the file.  If the stream is constructed by allocating
a filebuff and then opening it, nothing is written to the file.  Has anybody
run into the same problem ? Any good ideas what to do ?  All ideas will be
appreciated.
