Unused variable but no warning

It is strange that gcc does not complain about an unused variable in innd/perl.c:

/* From art.c.  Ew.  Need header parsing that doesn't use globals. */
extern char             *filterPath;

at the beginning of this file.
filterPath was previously used when the Path: header was parsed in this file
but it is no longer the case.

If I remove that extern declaration, gcc does not complain either.  Therefore,
I think it can be removed.
But it is strange that gcc does not see that during "make warnings".
