Hello there,
The short version -- how to set warning level just for one specific
file, or more exactly how to relax warning level for it?
The long version -- I try to work at maximum warning level
/including -Werror/ but lately I have to work with QT and this library
generates a lot of warnings. I have read on
http://www.artima.com/cppsource/ C++ Coding Standards and tried to do
something similar -- i.e. write a wrapper for all QT...

I tell C++ Compiler to use level 4 warning instead of level 3 warning so
all variables can be calculated accuracy with no prone error.
It will give you a warning like this.
unsigned short A = 0x8002;
unsigned short B = 0x7FFF;
unsigned short C = 0;
C = A + B; // Warning loss high byte conversion -- 0x8002 + 0x7FFF = 0x10002

In C++ there is a very useful function to programatically disable warnings
temporarily.
Can this be done in C# ?

in March, i posted a essay “What is Expressiveness in a Computer
Language”, archived at:
http://xahlee.org/perl-python/what_is_expresiveness.html
I was informed then that there is a academic paper written on this
subject.
On the Expressive Power of Programming Languages, by Matthias
Felleisen, 1990.

I have a macro that I use across the board for freeing ram. I'd like to
clean up my code so I don't get these warnings.
#define sfree(x) _internal_sfree((void **)&x)
#define _internal_sfree(x) ({ if(x && *x) { free(*x); *x=NULL; } })
void main() {
char *x = (char *) malloc(10);
int *y = (int *) malloc(10);

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
