Make sure to compile with DEBUG=1 so that the compiler flags needed to
emit debugging information will be enabled. Good luck!

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
