Building master on Cygwin with gcc-5.3.0 yields many "control reaches
end of non-void function" warnings. What's the best way to get rid of
these? Should I add return statements that will never be reached, like
this?

The tradition of hijacking the symbol 'lint' for GCC purposes has been
used for many years in several GNU packages. As the problem you mention
affects only optionally-generated warnings on non-GNU platforms, I
suspect nobody has cared until now about the issue. Anyway, I changed
Emacs master to use the symbol GCC_LINT instead; this should avoid the
collision in names.
Thanks. Closing.
