bug#12016: 24.1; ff-find-other-file is not considering cc-other-file-alist for .cxx files

[Surya Gullapalli]

I've set cc-other-file-alist like this

(setq cc-other-file-alist
      '(
        ("\\.cxx$" my-cxx-hxx-convert-fun) 
        ("\\.hxx$" my-cxx-hxx-convert-fun) 
        ("\\.c$" (".h"))
        ("\\.h$" (".c" ".cc" ".C" ".CC" ".cxx" ".cpp"))
        ))

When calling ff-find-other-file for a .hxx file, my-cxx-hxx-convert-fun
is getting called properly and I'm getting the expected list of
items. But when called ff-find-other-file for .cxx file,
my-cxx-hxx-convert-fun is not getting called at all and hence emacs is
uanble to determine the candidate files.

(I'm going through old bug reports that unfortunately got no response at
the time.)

I'm unable to reproduce this problem in Emacs 25.1 (and Emacs 28).

Are you still seeing this issue in recent Emacs versions?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
