As most if not all of the math library and docs are part of and shared with
newlib, most of the maintenance will be done in Linux, where these .so refs are

The Cygwin doc packaging will have to patch this to avoid using the other cased
variants of any man pages which are symlinks or only contain .so refs: the only
file currently matching those criteria is jn.3.gz.

Anyone can fix this locally by extracting the newlib doc from your Cygwin
mirror's downloaded tar case sensitively to your Cygwin root as:
$ /bin/tar -xvf
usr/share/man/man3/jN.3.gz -C /
