When running "make dist" (several times) today, I noticed the following:
- WARNING: Got bad config.guess from ftp.gnu.org (non-existent or empty)
- WARNING: using included versions for both config.sub and config.guess
Nevermind for the moment that the wget is NOT from ftp.gnu.org any longer.
The part that worried me is the "non-existent or empty" claim.
A quick look shows that logic in distscript.csh uses the non-portable "-s"
operator[1].
One should be using "-z" instead of "! -s":
