With this, fflush at least compiles on mingw:

This should be feasible, since a stream has a state when the buffer is empty
and the file descriptor is not block-ali

Hi Eric,
On Cygwin 2006 (/usr/bin/cygwin1.dll dated 2006-01-20), the test-fflush test
fails:
File offset is wrong.
FAIL: test-fflush.exe
In test-fflush.c line 70, the return value from lseek() is 10 instead of the
expected 5.
