//:
// \file
// \brief Include compiler's <iostream.h> in a uniform way.
// \author awf@robots.ox.ac.uk
//
// In particular, define the following
// \code
// vcl_ostream
// vcl_ios_X (as in ios::X)
// operator>>(vcl_ostream &, T &) for T in {signed char, bool}
// vcl_hex
// vcl_dec
// vcl_ws
// vcl_setprecision
// vcl_streampos
// vcl_streambuf
// vcl_streamsize
// vcl_cin
// vcl_cout
// vcl_cerr
// \endcode
//
// Include this to ensure the two are consistent.
#include "vcl_iosfwd.h"
// Notes to maintainers.
// The purpose of this file is to repair broken iostream
// headers. Thus in conditional logic, the compilers that
// behave in a non-standard way should be treated first, as
// special cases, and the #else arm should contain the
// appropriate action for an ISO compiler.
// On win32, <iostream.h> contains old crufty iostreams and
// <iostream> contains new standard ones. There is no iosfwd
// for the old ones and <string> includes the new iostreams.
// So we must avoid the old ones at any price.

#if defined(VCL_SGI_CC_720)
# include "sgi/vcl_iostream.h"
#else // -------------------- ISO
# include "iso/vcl_iostream.h"
#endif
// -------------------- miscellaneous fixes which can go at the end:
// Need std::ios::nocreate to avoid creating an empty file on
// attempts to read a non-existent one. Don't we? -- fsm
#if defined(VCL_VC50)
# undef vcl_ios_in
# define vcl_ios_in (std::ios::in | std::ios::nocreate)

// It seems that VC++ can show strange behaviour without this include:
#if defined(VCL_VC)
