• SUPPORT & USER GROUPS

• Name mangling for type bool is changed from _X to _N, in order to be more compatible with VC.
• Literal float support has now been brought in line with ANSI C99.
• Floating point constants for other than static initializations are not folded if the folding would result in any exception flags being raised. This is per C99. To always fold the constants anyway, use the -ff (fast float) flag.
• Fixed problems with hex long doubles.

• Hex floats no longer turned off by -A.
• Long longs no longer turned off by -A.
• // comments in C no longer turned off by -A.
• The default CPU target is now the Pentium Pro (-6), not the Pentium.

• Fixed problem with dllexport on function pointers.
• Added gc.h
• Added Hans Boehm garbage collector to rtl
• Added long double, %a and %A support to printf for win32

• Fixed 16 bit code gen bugs.
• Added iso646.h
• Added stdint.h
• Added stdbool.h
• Added va_copy() to stdarg.h
• Added isxxxx() floating point comparison macros to math.h

• Fixed spurious syntax error compiling some MFC code.

• Now with 32 bit X32 DOS extender support!
• Fixed code generator support for X32.

• Changed __i keyword to __imaginary due to numerous conflicts with existing code.

• Added support for __restrict pointer syntax.
• Added support for macros with variable & blank argument lists per C99.
• Added support for __func__ per C99 6.4.2.2.
• Added __FUNCTION__ predefined macro.
• Added __PRETTY_FUNCTION__ predefined macro.
• Fixed bug in wcscmp() for 0 length strings.
• -Aa switch to SC is now the default. There is no way to turn it off.
• Added _Complex and _Imaginary type support per C99.
• Renamed C++ complex class file complex.h to oldcomplex.h.
• Added new complex.h per C99.
• Added complex library functions per C99.
• Added isinf() per C99.
• Added long double support to isxxx() functions in fp.h.

• Added __DMC__ predefined macro.
• Added -d switch to generate make dependency information.
• Added debug statements.
• Added debug declarations.
• Added design by contract features.
• Added ability to embed C in HTML files.
• Added native support for 80 bit long doubles (Win32 only).
• Added support for CPU bit instructions via functions in bitops.h.
• Switch -mn is now the default instead of -ms.
• 16 bit preprocessor spp.exe no longer supported - use sppn.exe.

• Better Code Generation
• Merged C and C++ Compilers. They are now in the same executable. This saves disk space and testing time.

Added MMX Extensions

	New Intel MMX instructions now supported by the inline assembler.

Added Support for Alternative Names

	With -A and the C++ compiler, the alternative representations
	in the standard 2.9 are now supported. In the future, they will
	become the default, so don't use the following names otherwise:
	and and_eq bitand bitor compl not
	not_eq or or_eq xor xor_eq

Added -B[e|f|g|j] switches

	See "Definitive list of SC switches" for how they work. 
	The SCMSGS environment variable and SC.INI setting is no 
	longer supported.

Added #elseif directive, with same semantics as #elif.

Changed overload resolution rules to reflect ANSI C++ standard changes
regarding integral promotions vs integral conversions.

Added namespaces

Added -g5 switch
	See "Definitive list of SC switches".

Added #pragma setlocale("locale")
	See "Pragmas supported by SC/SC++".

Added _CPPRTTI and _CPPUNWIND predefined macros
	See "Predefined macros".

Added New Keywords
	explicit, mutable, typename - but the semantics of them aren't
	implemented.

Added __unaligned Keyword
	For unaligned pointer support for PowerPC. Ignored for Intel
	compiler.

Added Pentium Pro Instructions to Inline Assembler and OBJ2ASM.
	Added new P6 instructions:
		CMOVcc
		FCMOVcc
		FCOMI
		FCOMIP
		FUCOMI
		FUCOMIP
		RDMPC

Added -ND switch
	See "DEFINITIVE LIST OF SC SWITCHES", 
	and _MT and _DLL in "PREDEFINED MACROS".

-NLlibfile
	Added this switch. See "DEFINITIVE LIST OF SC SWITCHES".

__wacrtused
__wacrtused_con
	Added these for use in Win32 UNICODE apps. See "ACRTUSED".
