Thanks for the report, and sorry for the delay.  Short of any better
fix, I'm installing the following on HEAD and branch-1-9.

Do you know why Debian doesn't use the -Z option of patch?  
I always wondered.

2005-06-08  Alexandre Duret-Lutz  <address@hidden>

        * lib/am/texibuild.am (?GENERIC_INFO?%SOURCE_SUFFIX%%DEST_SUFFIX%):
        Do not backup any file if makeinfo is not installed.
        * lib/missing (makeinfo): Do not touch a missing info file.
        * tests/txinfo30.test: New file.
        * tests/Makefile.am (TESTS): Add txinfo30.test.
        Report from Bob Proulx.
