In some spare minutes I made a list of options and their behaviour. I
attach it here for your convenience.
Thanks for doing this research. They are closer than I thought.
Perl I could start hacking
Very unfortunately, I don't think it would be acceptable for GNU to have
install-info in Perl. The reason is that install-info is one of the
very few "basic utilities" listed in the GNU coding standards (see
below). Having it require Perl to be installed seems at odds with this.
I can just imagine rms trying to build GNU some day and having make
install fail because he doesn't have Perl (which he won't) ...
So I fear it has to stay in C. I agree it would be a whole lot easier
to implement in Perl :(. Even worse, the current source is (as usual) a
lot less modular/understandable than it might be.
So I guess this has to go on the someday list ...
Thanks,
Karl

7.2.2 Utilities in Makefiles
----------------------------
Write the Makefile commands (and any shell scripts, such as
`configure') to run in `sh', not in `csh'. Don't use any special
features of `ksh' or `bash'.
The `configure' script and the Makefile rules for building and
installation should not use any utilities directly except these:
cat cmp cp diff echo egrep expr false grep install-info
ln ls mkdir mv pwd rm rmdir sed sleep sort tar test touch true
[...]
