Oops, my bad.  The build that went wrong was an out-of-source build.  In 
both cases, I'd previously executed cmake in the source direcory by 
mistake.  Before OS upgrades, this never caused problems.  With the new 
OS and new compilers, the config headers in the source and out-of-source 
directories obviously differ and cause havoc.

In short: when building out of source, make sure your source dir is 
PRISTINE.

Thanks,
Charl
