Dear all,
I was looking at a simple code on an exercise question. In the code,
there is a conditional inclusion dependent on __GNUC__
#include <algorithm>
#include <iomanip>
#ifndef __GNUC__
#include <ios>
#endif
How can I get system specific macro names, like __GNUC__, for the
system I am working on. I do not need this but I was curious about it,
and googled for it but I have always found things related to
conditional compilation. If I am not mistaken, these are the names of
macros defined, correct me if I am wrong.
I use Debian Etch and gcc 4.1.12. Is there a way to get them directly
from command like, maybe this is off-topic :S

If the preceding sentence were a question, I'd answer it with "RTFM".
Your system and the compiler are supposed to come with a manual. So,
R it.

What does it mean "to get them directly from command like" (and even if
you meant "line")?

I think everyone who used Python will agree that its syntax is

However in Access 2000 it seems you have to build your menus by

macro for every single menu and sub menu. The old method would allow
me to include several menus (File/ print/ page setup ...) all within
one macro. Now it seems I...

I've been trying to track down explicit information about this for some time.
I know that the ANSI C standard specifies the __* and _* macro
namespace as reserved for the compiler implementation, and playing with
a handful of compilers I can find what those specific compilers predefine,
but is there any information out there on how that reserved namespace
should be used?
If I am writing some portable code what predefined macros should...

Does the length of my C variable names have any affect, performance-wise, on
my final executable program? I mean, once compiled, etc., is there any

number = 3;
n = 3;
I know its setting aside storage for the variable itself; does it also use
up more storage if the variable name is longer? I realize it would probably
take quite a lot of long variable names to make any impact if so, but I was

Hello all,
I tried to write a macro to check if a system is big endian or little endian
with no success. Don't get me wrong, I have no problem writing a function or
a one liner to do that, but I was trying to do it in a _macro_ with no
side-effect (no global variable declaration). I suspect this is not
possible.
Anyone cares to prove me wrong ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
