Is mips a big endian cpu?  I can't reproduce this on 
i386 or x86_64 hardware.

mips can be implemented as either big endian or little endian. I have an SGI
box, which is a big endian implementation. DEC built a line of mips
workstations that were little endian. There are separate versions of Linux for
each endianness.

I can confirm that on mips-linux-gnu (big-endian) 0 is printed while 1 is
printed on mipsel-linux-gnu (little-endian).  This happens both with 4.1
and current 4.3.

I don't see this problem on powerpc which is big-endian too.

Sorry, I *do* see the problem on powerpc.


(sid)832:[EMAIL PROTECTED]: ~/src] gfortran -fdefault-integer-8 t.f90 ; ./a.out
i = 0
(sid)833:[EMAIL PROTECTED]: ~/src] gfortran t.f90 ; ./a.out
i = 1
