This question was actually dumb, dmd and ldc do support MingW:
I should have created a .lib file instead of using the object 
file directly:

`g++ -c libs/webview/webview.cc -std=c++14 -Ilibs/webview2 
-static-libstdc++ -static-libgcc -DWEBVIEW_STATIC -o webview.o`

`ar r webview.lib webview.o`

... and used that with dmd/ldc instead.
For the duplicate symbols in ldc adding the flag 
`--mscrtlib=<libcmt[d]|msvcrt[d]>` worked.
