This patch requires another change in Cygwin.

For some reason, entirely lost in the mist of time, Cygwin exports the
cleanup_glue function.  It already did so when winsup and newlib sources
have been imported into the sourceware CVS repo, back in 2000.

At this point I'd usually say that we can't change that because backward
compatibility and yada yada, but it just doesn't make any sense to export
cleanup_glue, and never did.  At all.

So, instead of reverting cleanup_glue to non-static, let's pull this
through and let's drop it from the list of exported functions.

That means, this patch needs a tiny extension and the commit message
should mention that it's removing cleanup_glue from the list of exported
symbols.

Here's the diff of the required change, please add it to this patch:
