[BUG] Compiling errors when defining additional axes as rotational about marlin HOT 8 OPEN

I compile(verify) and upload Marlin onto my Arduino Due board with Arduino IDE 2.3.2 on Windows 11.

Please use VSCode with PlatformIO instead: Link.

Also, from our README:

You can still build Marlin with Arduino IDE, and we hope to improve the Arduino build experience, but at this time PlatformIO is the better choice.

from marlin.

Your configs & code snippets are all from 2.1.2.2.

Please download bugfix-2.1.x to test with the latest code and let us know if you're still having this issue.

I just downloaded the latest bugfix-2.1.x version and tested defining additional axes as rotational. New compiling errors occur:

\Marlin-bugfix-2.1.x\Marlin\src\lcd\HD44780\marlinui_HD44780.cpp: In static member function 'static void MenuItem_static::draw(uint8_t, FSTR_P, uint8_t, const char*)':
\Marlin-bugfix-2.1.x\Marlin\src\lcd\HD44780\marlinui_HD44780.cpp:1210:43: error: variable-sized object 'estr' may not be initialized
     char estr[calculateWidth(ftpl) + 3] = "\0";
                                           ^
exit status 1
Compilation error: variable-sized object 'estr' may not be initialized

I was able to fix the above by implementing these changes to "\Marlin-bugfix-2.1.x\Marlin\src\lcd\HD44780\marlinui_HD44780.cpp", (line 1210):

--char estr[calculateWidth(ftpl) + 3] = "\0";
++char estr[calculateWidth(ftpl) + 3];
++memset(estr, 0, (calculateWidth(ftpl) + 3)*(calculateWidth(ftpl) + 3)*sizeof(char));

But after that, the exact same pragma GCC diagnostics errors occur in "\Marlin-bugfix-2.1.x\\Marlin\src\module\temperature.cpp" (lines 3103 & 4117):

\Marlin-bugfix-2.1.x\Marlin\src\module\temperature.cpp:3103:26: error: missing binary operator before token "("
   #if __has_cpp_attribute(fallthrough)
                          ^
\Marlin-bugfix-2.1.x\Marlin\src\module\temperature.cpp:4117:28: error: missing binary operator before token "("
     #if __has_cpp_attribute(fallthrough)
                            ^

exit status 1

Compilation error: missing binary operator before token "("

which I was able to fix by doing the same changes to suppress pragma GCC diagnostics errors in the previous comment.

How are you compiling your build? Compiling works fine under macOS with VSCode + PlatformIO:

Thank you. I installed PlatformIO on my VSCode and managed to compile without errors.
