Re: [Attn: base-files maintainer] Changing /etc/profile to add more shell-dependent settings

No, this section is specific to zsh and probably even the wrong thing to
do -- /etc/profile is only ever intended to be run by POSIX compatible
shells (or shells in POSIX mode if they support that notion).  I've kept
it alive for the time being since nothing packaged in Cygwin depends on
it.  For anybody else using it for their personal customization it must
already be working.

Bash can use ".sh" with the proviso that you can only use the POSIX
subset of its functionality.  Other, non-POSIX, shells should implement
something similar in their own startup scripts.  Csh already does, I
don't know enough about fish to tell how to insert something into its
start-up.  IIRC, Zsh also has a way to run extra code besides just the
one in /etc/profile if you somehow need that.

Look again, and don't let yourself get distracted by the zsh specific
code.  :-)
