This refers to MS-Windows (mingw and cygwin).  I see that libperl was
also linked against in Texinfo 7.2 in this case, so this is not new.  However,
missing or deficient libperl shouldn't cause a build failure when it doesn't
have to (on platforms that aren't on MS-Windows).

I see, it seems fairly harmless.  Maybe it could be clearer that a directory
called "swig" does not depend on swig.  Maybe renaming it something like
"api_for_swig" would be enough.
