MinGW and wmain: undefined reference to `WinMain@16'

This is revisiting an issue that I thought I had already addressed, but apparently not.

I use MinGW toolchain, typically the TDM variant, to avoid issues with unavailable libraries.

I'm converting some of my Windows programs to Unicode, to provide support for Unicode filenames. However, I repeatedly have issues with the declaration of main(); when I change it to wmain(), the file compiles with no issues, but I get a linker error:

c:\tdm32\bin\g++ -Wall -s -O3 -c -Weffc++ -Wno-write-strings -DUNICODE -D_UNICODE media_list.cpp
c:\tdm32\bin\g++  media_list.o common.o qualify.o ext_lookup.o file_fmts.o conio_min.o  MediaInfoDll.o  -s -O3 -dUNICODE -d_UNICODE -o
MediaList.exe -lshlwapi
c:/tdm32/bin/../lib/gcc/mingw32/10.3.0/../../../../mingw32/bin/ld.exe: c:/tdm32/bin/../lib/gcc/mingw32/10.3.0/../../../libmingw32.a(main.o):(.text.startup+0xc0): undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status
make: *** [MediaList.exe] Error 1

When I previously attempted to address this issue, I was using the 64-bit TDM MinGW toolchain, and I was able to resolve this issue by using the -municode linker option. However, now I am converting another console application, and am using the 32-bit TDM (g++ V10.3.0), because I'm using an addon DLL that does not support 64-bit... Unfortunately, that -municode linker option is not supported in this toolchain.

Is there some other way to resolve this issue??

I found the solution to this issue on Github;
This short, simple code fragment solved the problem completely:
