This is wrong, it should be the full Windows file name starting with a
drive letter.  Looks like the epaths-force-w32 target in the top-level
Makefile is not working correctly for some reason.  It should convert
the value of srcdir into a Windows d:/foo/bar format, and then replace
@SRC@ in nt/epaths.nt with that value.

That is correct.

I'd try this instead:

  set auto-load safe-path c:/msys/home/dani

(I always disable this nuisance by using "/" as the argument.)
