This is necessary in order to make help2man's LD_PRELOAD hack work.
bindtextdomain.so is meant to override a couple of gettext functions (in
order to use uninstalled message catalogs), but that won't work on
Cygwin unless the DLL names match, which necessitated adding
pass-through wrappers to the other functions as well.  I suggest looking
at my patches if you want to understand exactly what's happening here.

Since the LD_PRELOAD hack will only be used briefly and rarely, and the
real cygintl-8.dll is already loaded as a dependency of sh/bash, I don't
see any practical problem here; I certainly didn't encounter any when
testing this hack.
