cygwin init

[Marco Atzeri]

Hi All,
trying to solve an issue about image loading

http://sourceforge.net/mailarchive/message.php?msg_id=20081108035356.13562.qmail%40web3813.mail.bbt.yahoo.co.jp

I found that the "cygwin_init" in "src/sysdep.cc"
has a strange modification of TMPDIR to Windows
directory name that can create problem 

octave:1> getenv("TMPDIR")
    ans = C:/cygwin/tmp
instead of a plain
    ans = /tmp
that I should expect.

removing the modification with the attached patch
creates no visible issue (all test Passed)
and solve the image loading.

Do someone knows why the translation of TMPDIR
is in place for cygwin ?

Regards
Marco Atzeri
