file not working on executables?

[Luke Kendall <luke dot kendall at cisra dot canon dot com dot au>]

I installed the latest Cygwin a couple of days ago.  "file" now
produces no information for binary executables.  Anyone else seeing
this problem?  (I checked that "file" is /usr/bin/file.)

$ file /usr/bin/ls.exe
/usr/bin/ls.exe: 
$ file /cygdrive/c/WINDOWS/system32/net.exe
/cygdrive/c/WINDOWS/system32/net.exe: 
$ file /etc/profile
/etc/profile: ASCII English text
$ file ~/.profile
/home/luke/.profile: Bourne shell script text executable

A bit odd that it got /etc/profile wrong, too.

cygcheck -s is attached.  I think my magic files are okay.  Here's part
of an strace of ls /usr/bin/ls.exe
