Details:

first identified in bug #62105 when using the editor in debug mode. if  using
F9 to execute a code block an error is indicated pointing to the temporary
file created for executing the code.  However, despite tmpdir being set, the
temp file appears to be located in the system TEMP location. Unsure if this is
an issue with the GUI or with the debug mode, and if it affects more than
windows (verified on 6.4.0 on Windows 10).  This seems similiar to bug #55814,
where mkoctfile was ignoring tmpdir, but that was fixed a few versions ago.

to reproduce:


*create c:\octave\temp*

>> getenv('temp')
ans = C:\Users\<USERNAME_in8.3format>\AppData\Local\Temp

>> getenv('tmp')
ans = C:\Users\<USERNAME_in8.3format>\AppData\Local\Temp

>> setenv('tmpdir', 'c:\octave\temp')

>> tempdir
ans = c:\Octave\Temp\

>> edit mean

*set breakpoint at first line of code - line 94*

>> mean(1)
stopped in mean at line 94 [C:\Octave\octave-6.4.0-w64\
mingw64\share\octave\6.4.0\m\statistics\mean.m]
94:   if (nargin < 1 || nargin > 4)

*highilght uninitialized variable 'nd' on line 101, press F9*

debug> nd
error: 'nd' undefined near line 1, column 1
error: called from
    C:/Users/<USERNAME>/AppData/Local/Temp/octave/octave
_klgahA.m at line 1 column 1

debug> tempdir
ans = c:\octave\temp
