Is the key reason for not making the change because there may be
requests from others to make similar changes? That doesn't seem like
sound technical decision making. Each request would surely be
evaluated on its own merit.

It is certainly the responsibility of user-level code developers to
fix their mistakes, but in this case it's an established practice on
another system. The requested change does little to alter the
maintainability of glibc, but allows more code to be ported to a
platform that I use every day.

Yes, the slope is slippery, but this seems to be a mechanical change
that is not yet near the slippery part, and benefits all users of

* Enables porting more code to run on platforms that use glibc.
* Easy to verify patch with little maintenance impact.

* Possible future requests to make similar changes need to be evaluated.

This seems like a win to me.
