There was a merge error when porting some patch from master back to
branch-1-10.  This caused some changes to the manual to be put in the
branch which shouldn't have been there.  These changes have slipped
into 1.10.2, unfortunately.  It has been fixed since, but I haven't had
time to release 1.10.3 yet.

Sorry about the inconvenience.  git master contains AM_COND_IF only,
it is very new (and serve rather special needs only).  I.e., if all
you need is to evaluate some conditional inside, then
you can simply repeat its expression:

AM_CONDITIONAL([COND], [test "$foo" = bar])
if test "$foo" = bar; then

Only if the second ellipsis in above code is to contain something like

then will you have to use AM_COND_IF.  For other cases it is merely
syntactic sugar.
