A couple of patches w.r.t. the target `path-check'

[Stefano Lattarini]

Hello automakers.

I will soon post a couple of simple patches regarding the maintainer-specific
target `path-check'.  The patches solve a couple of (potential and very minor)
portability problems.

However, I noticed that a lot of failures crop up with `make path-check',
either with or without my patches installed (these failures are listed
below).  So I have a question: is the `path-check' target still relevant?
Or equivalently: is the Automake distribution really still expected to be
successfully deployed on a host with the 14-characters length limit for
filenames?  I personally don't even know if a such system is still used
in practice, but I have no experience with ancient or "exotic" hosts at
all, so you might know better.

Regards,
    Stefano
