Generally this involves indexing the symbols

There has been some debate in the Autoconf

Windows does permit a program to use a
forward slash to separate directories when calling routines such as
`fopen'. However, Windows users do not expect to type forward
slashes when they enter file names, and they do not expect to see
forward slashes when a file name is printed.
