I think we would all be interested in seeing Marcel's reply!

I don't know if GMP-ECPP would suit - but I'd be happy for you to try

I compiled gmp-ecpp on a Linux 64 bit system, but didn't got it static compiled, libgmpxx.a is missing. Is there a way to get a static version of it for Suse Linux?

How long does it needs to compute a prp certificate for a 500 digit prp?

You are correct that it needs libgmpxx.a as well as libgmp.a
If you compile with the flags -lgmpxx -lgmp then this will dynamically link, as you say.
I _thought_ that if you added the flag -static you would get a static build, but this probably requires that both the gmp libs are available in static form somewhere, so maybe one would need to specifically recompile the gmp library to create these (with --enable-cxx in the ./configure step).
However the way I've always got a static build is to pass the full paths to the gmp libs at link time.
On a modern core 500-digit will take (order of magnitude) 1 hour, but it can be variable.

Default gmp-ecpp

For the time being I compiled it with shared libs and -O3. I run it with
./atkin243 -Q -s 1367903930 < in1 > out1
for a 461 digit PRP. But it is now running since 5 hours on a i7?

Hmmmmm that does seem a little slow. Are you getting any output at all? For a number that small you might find the (additional) switch -B 2000 will speed things up.

Angry Still no reply, EVEN AFTER 4-5 MONTHS!!

Marcel STILL hasn't replied to my E-mail! If he doesn't reply, I'm going to keep sending him mail every 4-6 months UNTIL either I get a reply OR he makes another Windows version!

Now it finished after ~ 2 hours. Input and output are here https://dl.dropboxusercontent.com/u/6717960/result1.zip.

For which numbers should I use -B 2000?

Thanks for that output, which looks correct. (though you can also run with the -q rather than -Q if you want a little more detail)
I would (vaguely) suggest -B 2000 for any number under 1000-digits that otherwise seems to be taking too long
