Most probably.  It also could be indirectly caused by your recipes.

Could be, you should be able to use Process Explorer to see who holds
a handle on the files that fail to be deleted.

In general, killing subprocesses is problematic on Windows, because
only child processes can be killed, the grandchildren cannot.
Therefore, rearranging your build commands might make the issue go
away.

Well, I'd start by posting a minimal Makefile and auxiliary files that
allow to reproduce the issue.

Another approach would be to try the MinGW build here:

  https://sourceforge.net/projects/ezwinports/files/?source=navbar

where you can also find Make built with Guile support, something I
don't think MSYS2 guys offer.
