//
// ADDITIONS FOR COMEAU C++, made by Comeau Computing.
// We can be reached through [e-mail]
// You shouldn't need to change anything below here for Comeau C++.
// If you do, please tell us at [e-mail]
//
// Changes made here, AND THROUGH ALL FILES, based upon the __COMO__ macro
// (and SIMILAR NAMES INVOLVING COMO).... no doubt some of this will
// change as SGI integrates the changes into their code base since
// some changes are not really Comeau C++ specific, but required to
// make the SGI code compliant with Standard C++).
//
// Testing was done with Comeau C++ 4.2.44 and 4.2.45.2.  Changes were made for
// both Comeau relaxed mode and Comeau strict mode, especially for end user code
// (that is, some of the .cxx files cannot compile in strict mode, because they
// contain extensions to Standard C++, however their object code forms can
// be used once compiled in relaxed mode, even if the end user code uses
// strict mode).
//
// These changes may also work for some earlier versions of Comeau C++,
// though we have not tested them.
//
// Actual mods made under RedHat 6.1 LINUX, should be ok with SuSE too and
// other LINUX's, and older Caldera LINUX, Solaris/SPARC, SunOS, SCO UNIX,
// and NetBSD. Other platforms may be added.  Comeau will also perform
// custom ports for you.
//
// Check libcomo details at http://www.comeaucomputing.com/libcomo and
// http://www.comeaucomputing.com
//
// History of Comeau changes (this is rough, as work was often going on in parallel):
// BETA1 July 14, 2000, Initial port for RedHat 6.1 INTEL/ELF
// BETA2 Aug   4, 2000, Stronger RedHat support
//                      Support for Comeau strict mode for end user code
// BETA3 Aug  22, 2000, Support for other LINUX/INTEL/ELF's, including older ones
// BETA4 Sept  2, 2000, Initial support for SCO UNIX + other UNIX x86 SVR3's
//                      Stronger support for end user Comeau strict mode
// BETA5 Oct   5, 2000, Initial support for Solaris/SPARC
//                      More SCO support (though still incomplete)
// BETA6 Feb   5, 2001, Minor mods to accomodate Comeau C++ 4.2.45.1
// BETA7 Mar  13, 2001, Verified with Comeau C++ 4.2.45.2
//                      Minor NetBSD support
// BETA8 Apr   1. 2001, Initial support for SunOS/SPARC
// BETA9 Apr   7, 2001, Stronger SCO support + other UNIX x86 SVR3's
//                      Mods for an fpos_t problem for some LINUXes
//                      Mods since Destroy did not work in strict mode
// BETA10 Apr  12. 2001, Stronger NetBSD support
//
// PLANNED:
// BETAx TBA  TBA, 2001, NetBSD, UNIXWARE, and Windows support expected
