cygwin vs linux: output differences

[Yves Krähenbühl - MTD <yves dot krahenbuhl at m-td dot com>]

Same programme compiled under Cygwin writes output which differs form its
LINUX-compiled version


I apologise in advance if the question is too trivial but I am a simple user
and not a programmer.
I have written a small FORTRAN programme which reads and writes numbers in a
file:

program toto
implicit none
integer ifi1,a,b,c
ifi1=10
b=6
open(ifi1,file='toto.dat',status='unknown')
read(ifi1,100)a
print*,a
write(ifi1,100)b
read(ifi1,100)c
print*,c
close(ifi1)
100 format(i3)
end

Starting form the file toto.dat:
1
2
3
4
5
6

Under LINUX the programme re-writes the number 6 on the second line, and the
resulting toto.dat file is:
1
6

whereas under CYGWIN (cygwin-1.5.4-1 from 17.09.2003) the number 6 is
written after lhe last line and one gets the following toto.dat:
1
2
3
4
5
6
6

Can someone tell me how to avoid that problem under CYGWIN ?

Thank you in advance
