This is a bad idea. While com_err is certainly better than a completely
ad-hoc system, it simply cannot be adapted to certain tasks. Error
messages from the various libaries in my kstuff package, for instance,
are multi-level: if getavenrun() fails because kmemcpy() failed because
kmeminit() couldn't open /dev/kmem, strerr(avenrunstrerr) will return
this string:

  "cannot read avenrun: cannot open /dev/kmem: Permission denied"

My strerr library handles this. Of course, com_err addresses some issues
that strerr doesn't. The point is that it would be a mistake for GNU to
standardize on one error-handling library or another, as the technology
is still under development.
