humph. system.h change pushed prematurely

[Jim Meyering]

Somehow I managed to push this change.  Not only does it lack a
ChangeLog entry, but it should have been included as part of Paul's
upcoming stat.st_size-guard-improving changes.  It shouldn't have been
committed separately.  I did commit it locally, just to have a record
of it, but did not intend to push it.

Sorry.
