CVS coreutils doesn't build due to xalloc.h reversion?

[Paul Eggert]

CVS coreutils currently doesn't build out of the box since some of the
code uses X2REALLOC and X2NREALLOC but these macros were removed from
xalloc.h.  Was the removal intentional?  If so, uses of X2REALLOC need
to be replaced by x2realloc elsewhere.

Personally I'm becoming more inclined to not use those macros, as in
practice I'm finding the readability confusion to be more than any
potential reliability improvement.  But it's not a big deal either
way.

Or perhaps you meant to move the macro defns to system.h?  That would
be fine as well, and a bit more modular.
