$ LANG=de_AT.UTF-8
$ echo 'z:/' | egrep '^(/|[A-z]:/)'
egrep: Das Ende des angegebenen Intervalls ist nicht gültig
$ echo 'z:/' | egrep '^(/|[A-Za-z]:/)'
z:/
$ export LC_ALL=C
$ echo 'z:/' | egrep '^(/|[A-z]:/)'
z:/
$

So that means that this bug is due to collation order, and as
you wrote yesterday the interval should be changed to A-Za-z.

The egrep thing is there to detect if a filename is absolute,
i.e. starting with "/" as in "/usr/bin/true" (unix style), or
"C:/" (or another device letter) as in
"C:/WINDOWS/SYSTEM32/FILE.DLL" (Dos/Windows style).

As written in "man grep":

 To obtain the traditional interpretation of bracket
 expressions, you can use the C locale by setting the
 LC_ALL environment variable to the value C.

we can go around this bug by setting LC_ALL to C.

This bug is fixed in [1]:

-  echo "$command_line_filename" | $EGREP '^(/|[A-z]:/)' >&6 \
+  echo "$command_line_filename" | LC_ALL=C $EGREP '^(/|[A-Za-z]:/)' >&6 \

We might go around the bug with the attaced patch (texi2dvi is called 
from texi2pdf), but I have not had time to test it.
