Don,

   That's what I assumed; a version of c++, which is installed here by
default. Perhaps not that verision, but ...

   Since the configuration finds C++11 support available and a sufficiently
current version of gdal the warning/errors make no sense to me.

   FWIW, there's no issue compiling/using gdal on slackware; I've done so for
many years.
