[fpc-pascal] can someone please email me a zipped hello world binary program MIPS big endian for testing on my MIPS hardware?

Our gateway is dropping some messages due to attachments or something. 
Dennis, note the archives at 
http://lists.freepascal.org/lists/fpc-pascal/ and

OK, you should have them but I would say that this isn't easy for me at 
the moment: my host system is too slow to be realistic and booting the 
two targets took around an hour.

The compiler was 2.7.1 (trunk) as of about revision 23218. In practical 
terms I'd suggest starting off with the current trunk from svn and only 
trying an older revision if really necessary.

If these don't work for you then I think we need to work out what's 
going wrong, in case it's a general OpenWRT thing.

Note below for the big-endian system:

On my email etc. system:

$ cksum ./test-mips-*
2200884524 69468 ./test-mips-lsb
3420485397 68988 ./test-mips-msb

I've sent these in a tarball. I trust that you will accept that if the 
files arrive with the correct checksums that they've run successfully 
for me here.
