Someone with build system experience could modify the build of the toolchain
binaries to include a call to windres to add the manifest. This would just be
gcc itself and not what gcc produces. I guess maybe the binutils executables
would benefit also.

I would suspect this is a standard issue with all mingw projects so maybe it is
best to talk with them on how to solve this overall.

I've used the manifest tool from Visual C++ (mt.exe) to inject this manifest:





http://schemas.microsoft.com/SMI/2016/WindowsSettings;>
true




with the command line:
mt.exe -nologo -manifest "cc1plus.exe.manifest"
-outputresource:"cc1plus.exe;#1"

And I was able to compile the hello.cpp source file!
