[uClibc]fressh-0.3 works on mipsel. Thanks!

[Joseph Chiu]

Hi Matthew,

Wow - Thanks for that fressh patch.  I was able to use it to cross-compile
fressh for mipsel, something that's been bugging me for quite a while.

I just had a few more bumps -- my mipsel-uclibc-gcc (built against
gcc-3.0.4) complained about uninitialized variables and multiline literals;
and uclibc (perhaps only on MIPS?) returned NULL's for malloc(0).

I fudged the malloc(0) problem by always allocating an extra byte.

The resulting static sshd is just under 450 Kbytes, and seems to work great.
Not exactly tiny, but better than what I had before.

Joseph

Yes, those are both on.

Attached is the patch I used to compile a static version of fressh, which is
to be applied against http://www.fressh.org/fressh-0.3.1.tar.gz .  Also the
ltrace and strace outputs from running:

./sshd -Ddk -h sshd.key -p 2222

and then sshing from another machine where the RSA key matches.
