When cross compiling the host file(1) utility is used to compile the magic.
As the file(1) included internally in RPM is slightly older, the latest
version of file(1) at least chokes on some of the mime entries and b0rks
out...

The file(1) changelog entry reads as follows...
2008-04-04 11:00 Christos Zoulas <[EMAIL PROTECTED]>
* >= <= is not supported, so fix the magic and warn about it.
reported by: Thien-Thi Nguyen <[EMAIL PROTECTED]>
It seems though that these are not warnings and have a similar effect as
-Werror (ie. non 0 exit status), but anyway.
I've patched the mime sources for the internal file(1) utility and
attached the patch, this makes it compatible with both the internal and
latest file(1) utility :)
Jeff, can you let me know if its ok to commit.
