texi2dvi issue with cd_dir

[d . gerbet]

Dear developers,

after updating to the new version
$ texi2dvi --version
texi2dvi (GNU Texinfo 6.1+dev) 7174

of texi2dvi the paths to all files were screwed up. I traced this
problem up to the function cd_dir(), which should, as far as I can
imagine, update the variables in $path_vars. But the line
---
248 : eval "case \"$$cdd_dir\" in

will append the PID in front of the string 'cdd_dir' and has never a '/'
as iths first character. For this reason any absolute path ${!cdd_dir}
will be prefixed by '/../.. ...' which results in a garbage. Changing to
---
248 : eval "case \"${!cdd_dir}\" in

will detect the absolute path. However, the prefix will be appended to
relative paths, if cd'd into an absolute path. 

To reproduce the problem try to compile a document foo.tex with the
command
$ texi2pdf -D --build-dir=/tmp/bar foo.tex 2>bar

(the output 'bar' is appended to this mail)
Note the absolute path given by '--build-dir='. 

I could fix the problem for me by replacing all relative paths by
absolute ones, but I think you had a reason (DOS?) for the update of
variables instead of prefering absolute paths. 

Yours sincerely

Daniel Gerbet
