Under Cygwin, I ln -rs custom local Cygwin scripts and exes in:
added at the head of the Cygwin PATH,
and to keep them separate from Cygwin components, put custom local Windows user
scripts and exes in:
added after all Cygwin dirs in PATH, before other Windows dirs.
I keep Windows system specific scripts e.g. .cmd, .reg and exes requiring
elevation in:
separate from the unprivileged components.
I add /usr/local/bin/ to the head of the cron PATH, and /home/.../bin/ to the
tail of the cron PATH, so everything used in cron jobs is there; I run
everything in Scheduled tasks from C:\usr\local\bin\ for similar reasons.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
