I noticed these on cygwin, when using ./configure -C.

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       config.cache
#       src/cmp.exe
#       src/diff.exe
#       src/diff3.exe
#       src/sdiff.exe

Don't work too hard, make some time for fun as well!
