visual C++ 6

[Ioannis Vranos]

A bit off topic, but does anyone know if Visual C++ 6 supports the
9899:1995, or only the 9899:1990?

As far as I can recall, all that C95 added was <iso646.h- which, again as
far as I recall, VC6 doesn't provide (but I could be wrong about that, of
course).

Visual Studio swprintf() is not the standard one, no idea
what else is incompatible. Just forget about C95; it is not
C90 plus wide char api, it's C99 minus VLA. I suppose you
don't want C99 for obvious reasons yet you need wide char
api so you think you want C95; if it's really the case
then C90 *plus* visual studio CRT is quite enough, you
won't use wide char api on unix anyway.

The 1995 amendment (ANSI/ISO/IEC 9899-1990/AM 1-1995) makes the
following changes to C90:

Adds digraphs
<: :<& &%: %:%:
as synonyms for
[ ] { } # ##

Updates __STD_VERSION__ to 199409L

Adds <iso646.h>, required for both freestanding and hosted
implementations

Adds <wctype.hand <wchar.h>, required only for hosted
implementations

Adds EILSEQ to <errno.h>

Makes some adjustments to the description of <stdio.hto allow
for wide characters.

In summary, bug fixes to C90 + 3 new standard header files: <wchar.h>,
<wctype.hand <iso646.h>.

I think you are wrong. C95 is Amendment 1 of C90. Nothing to do with the
new stuff of C999, like long long, builtmin complex types etc.

The wide-character version of printf() in C95 is wprintf() declared in
wchar.h, and the rest of the new wide-character support is <wctype.h>
that provides the wide-character equivalents of the <ctype.hfacilit ies.

Actually VC++ 6 doesn't complain when I #include all of <wchar.h>,
<wctype.hand <iso646.h>. I am not sure it supports C95 completely though.

C95 is *much* closer to C90 than it is to C99. In other words, the
C99 standard added much more to the language than the C95 amendment
did.

C95 really is just C90 plus the wide character API, plus a couple of
other very minor changes.

In fact C95 is so close to C90 that, AFAICS, gcc does not support
conformance to C90, only to C95.

Yep. But if you look at conformance of popular compilers
(== "visual studio") then C95 is C99 minus VLA, that is,
not supported.
I guess "VLA" doesn't quite mean all language changes
from C99, but it doesn't really matter ;)

Visual C++ 2008 supports C95 100%.

C95 is *much* closer to C90 than it is to C99. In other words, the
C99 standard added much more to the language than the C95 amendment
did.

You are right, according to MSDN Visual Studio 2005
and newer conform to C95, and you need to define
_CRT_NON_CONFOR MING_SWPRINTFS to get the old non-C99
swprintf. Does someone know if the next C++ standard
is going to have C99-compatible variadic macros and
VLA? If it is, then perhaps MS will support C99 too,
some day.
