Yes, thanks.  I resolved this issue.  Somehow the timestamps on my system 
files were set to the year 2024.  I have no idea how it happened (it is a 
local filesystem), but touching all files with the incorrect timestamp 

I blamed the project on autoconf/automake because the one 
non-autoconf/automake project I tried didn't include any system headers.  Go 
figure, eh?

Thanks for the response.
