MINGW-packages: latexmk/runscript doesn't handle arguments correctly in mingw64

When trying to pass arguments to runscript or trying to call latexmk directly from command line, it can’t seem to interpret the arguments correctly. I run this command directly where main two.tex is.

C:\Users\simon\Downloads\test\SSB Build>latexmk -verbose -file-line-error -synctex=1 -interaction=nonstopmode -pdf -pvc  "main two.tex"
C:\SK\msys64\mingw64\bin\runscript.tlu:935: C:\SK\msys64\mingw64\bin\runscript.tlu:581: unknown option: -verbose
runscript wrapper utility (rev. 54353, 2020-03-16)
usage:   runscript script-name [arguments]
try -help [-v] for more information

this all happens while mingw64/bin is in PATH. I’ve tried to replicate the issue with a standalone texlive installation, but when I do that it compiles correctly. It also works if there are no space in my filenames so this works. So this:

C:\Users\simon\Downloads\test\SSB Build>latexmk -verbose -file-line-error -synctex=1 -interaction=nonstopmode -pdf -pvc  "main.tex"

compiles correctly.

I also seem to have the problem that I can’t invoke C:\SK\msys64\mingw64\bin\latexmk.exe unless ming64\bin is in my PATH.
