#61244: popt @1.18_0: build fails on 10.5_ppc
---------------------------+--------------------

     Type:  defect         |     Status:  new
 Priority:  Normal         |  Milestone:
Component:  ports          |    Version:  2.6.3
 Keywords:                 |       Port:  popt
---------------------------+--------------------
 Installing popt 1.18 on a 10.5 PPC system initiates a download and install
 of gcc7, presumably due to the inclusion of `compiler.c_standard 2011`.
 From the GitHub history, this addition appears to have been made to
 correct a warning on 10.7 (https://github.com/macports/macports-
 ports/commits/master/devel/popt/Portfile).

 Although the gcc installation is still running on my system, it appears
 from https://ports.macports.org/port/gcc7/summary that gcc7 fails to build
 on 10.5_ppc, and ultimately, the popt 1.18 install will also fail.

 Is `compiler.c_standard 2011` needed or can it be omitted from the port to
 allow popt to continue to build on older versions of MacOS?
