Hi there!
I've been having a lot of difficult trying to figure out a way to convert
a terminated char array to a system::string for use in Visual C++ .NET
2003.
This is necessary because I have some legcay C code that needs to process
a string taken from a textbox, then I need to re-display the string as the
textbox->Text. I easily found how to convert from system::string to char
but I can't figure out how to go the other way!!

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
