Steve and Sandeep, Can you try gcc -v instead and let me know what that outputs?
I just checked our Debian PostGIS bot, and she's running gcc 5.2.1 and think she's running the newest of any of our bots . So I can 't rule out a newer gcc at fault here. However if I do gcc -V, I get an error on her too, so that's not the issue here: -- gcc: error: unrecognized command line option â?~-Vâ?T gcc: fatal error: no input files compilation terminated. However, lower case -v (which is what I think configure uses, works just fine). gcc -v outputs: Using built-in specs.

Thanks, Regina ----- From: Stephen Woodbridge Date: Fri, Jul 7, 2017 at 2:09 PM I get the same error running on Ubuntu 16.04 with: $ gcc -V gcc: error: unrecognized command line option ‘-V’ gcc: fatal error: no input files compilation terminated.
