This won't work in cygwin - there, \ and / are synonymous for directory
separators, and 'touch src/\' will successfully touch the directory src.
 To correctly rule out cygwin, you need to try touching a longer
pattern, as in:

touch src/a"$odd_name"a

such that the touch will fail on cygwin (directory src/a does not exist,
so we can't create src/a\a aka. src/a/a) and correctly be skipped for
this test.
