The default directory for installing eCos on Windows (usually C:\Program Files\Cygnus Solutions\eCos) is different from that on UNIX (usually /usr/local/ecos-1.2.1). Since many command line examples in the tutorials use these paths, this default (base) directory will be shown as BASE_DIR.
Windows and UNIX have similar file system syntax, but the MS-DOS command interpreter on Windows uses the backslash character (\) as a path separator, while UNIX and POSIX shells use the forward slash (/).
This document will use the POSIX shell convention of forward slashes.
