No, actually this does not work, since the expansion of %b is still an
absolute pathname, rather than a relative pathname.  The only difference
is that the file extension is removed.  Here's a snippet from my
*trace-output* buffer when I trace the shell-command function:

command="makeindex -o
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.ind
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.idx"

The entry from my org-latex-to-pdf-process is:

"makeindex -o %b.ind %b.idx"

So using the basename is orthogonal to the underlying problem, which is
that absolute pathnames are always used.

When I restore the openout_any = p setting, I see:

rpg% makeindex -o
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.ind
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.idx


makeindex: Not writing to
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.ind
(openout_any = p).
Can't create output index file
/Users/rpg/obtw/obtw-trunk/memos/plan-representation/manual.ind.

Note that this isn't something one needs any org-mode testing to verify
--- you can just figure out what %b will expand to, and test
interactively with the shell using makeindex or bibtex, if you have a
recent texlive, with the paranoid settings.

The only "solution" I know (aside from disabling the texmf.cnf security
setting) would be to have org ensure that its CWD is the document
directory when running these programs and use relative pathnames.  I
don't know that this solution is compatible with correct use of
EXPORT_FILE_NAME, however....

This seems like a very crippling security setting -- it would break many
plausible uses of the tex suite when they are run under program control
(I could easily imagine scenarios with make that would result in the use
of absolute pathnames, too); I'm surprised it was made.

Best,
