Hi Ivan,

Actually, by getting an answer on another issue concerning updates of Git for 
Windows, I managed to solve this issue for me.
As can be seen here (https://github.com/git-for-windows/git/issues/4591), both 
issues were related to a mispecification of my ComSpec environment variable. 
Its value should be a single path to the cmd.exe file and no semi-columns 
neither.
With this done, I could also install again R packages from source. However, I 
am not sure how I ended up messing up this ComSpec variable in the first place 
:-/
But now it seems to be fixed.

Best regards,
Christophe
