## It is wrong to have 'info' files dependent on %DIRSTAMP%, because
## 'info' files are distributed and %DIRSTAMP% isn't: a distributed file
## should never be dependent upon a non-distributed built file.

## Back up the info files before running makeinfo. This is the cheapest
## way to ensure that
## 1) If the texinfo file shrinks (or if you start using --no-split),
##    you'll not be left with some dead info files lying around -- dead
##    files which would end up in the distribution.
## 2) If the texinfo file has some minor mistakes which cause makeinfo
##    to fail, the info files are not removed.  (They are needed by the
##    developer while he writes documentation.)
## *.iNN files are used on DJGPP.  See the comments in install-info-am
