Most .exe magic is already inside cygwin. In particular, CVS cygwin
(which will become 1.7.0) has a transparent_exe option that makes this all
even cleaner, without application specific knowledge. Coreutils is
special, in that it tends to do a lot of low-level tasks where the .exe
magic provided by cygwin is not always smart enough (for example, cp
/bin/bash /bin/sh needs to add .exe), at the expense of making usage
patterns of more common upper-level applications do the right thing by
default.
But the real problem reported by this thread has nothing to do with .exe
magic after all. Rather, it had to do with a non-compliant implementation
of open(O_CREAT|O_EXCL). In other words, to date, I have not had to teach
tar about any special .exe magic.
