I don't agree! It's nice to have only one environment variable TMPDIR
for all programs!

I reviewed your patch and have some remarks now:

  1) I think generated filename must be returned anyway. Temporary files must
     be unlinked after use, but it is possible only if a filename is known.
  2) This filenames are constructed by g_strconcat (), so they must be 
     g_free()d, not free()d. (ext.c and user.c)
  3) Optionally, may be it is more right to assign pname with NULL on error.

Andrew.
