[File] '--compile' regression in 5.46,5.48

[Mark Geisert]

Hi folks,
I'm a Cygwin maintainer.  A Cygwin user reported this to us...

BUG: /bin/file generates lots of warnings when compiling the default magic 
file:

$ uname -r
3.7.0-0.502.g31bf91f867c5.x86_64
$ file --version
file-5.46
magic file from /usr/share/misc/magic

That was file 5.46.  I tried building 5.48 and found the same regression. 
File 5.44 does not have this issue.

Cygwin 3.7.0 (pre-release test build), gcc/g++ 13.4.  Let me know if more 
information is needed.
Thanks much,
