This appears to be an issue with make 4.  Using make 3.82.90 under
recent Cygwin "fixes" the issue.  "Fixes" in quotes, because this might
be a result of how more recent make versions handle I/O.  This could
be a deliberate decision in terms of flushing output to a file.
Then again, it's rather puzzeling that this affects a file only opened
by the subshell.

Marco, do you see a chance trying to find out why this occurs?


Thanks,
