Microsoft Visual Studio 2005 Version 8.0.50727.762 (SP.050727-7600)
How do I get rid of "Warning C4307: '-' : integral constant overflow" from
the following macro?
#define d_ReturnMax(I_iTypeSize)\
( (int64(1)<<((I_iTypeSize*8)-1))-1)
There NO warnings when done as a function:
int64 d_ReturnMax(int64 I_iTypeSize)
{ return (1<<((I_iTypeSize*8)-1))-1;}

"Comparison to integral constant is useless; the constant is outside the
range of type 'int'"
How can I fix this compiler warning, please, for the following pseudocode?
int m_nError;
m_nError = somedriverapi.DoSomething();
if (m_nError != 0x8010002F) foobar; << compiler warning here
thankyou

Is the following legal?
void fun(int N) {
int arr;
}
gcc and Digital Mars accept it, but msvc complains that it wants a
constant expression.

C/C++ language proposal:
Change the 'case expression' from "integral constant-expression" to "integral expression"
The C++ Standard (ISO/IEC 14882, Second edition, 2003-10-15)
says under 6.4.2(2) :
case constant-expression :
I propose that the case expression of the switch statement
be changed from "integral constant-expression" to "integral expression".

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
