#57242: ragel @7.0.0.11: libstdc++ not available on Mojave
--------------------+--------------------
 Reporter:  pguyot  |      Owner:  (none)
     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:
 Keywords:  mojave  |       Port:  ragel
--------------------+--------------------
 ragel depends on libstdc++ because colm generates (unused for ragel)
 includes of ext/stdio_filebuf.h

 This is commented in Portfile:

 {{{
 # fatal error: 'ext/stdio_filebuf.h' file not found
 configure.cxx_stdlib libstdc++
 }}}

 libstdc++ is not installed on Mojave and build fails:

 Not sure if colm should be patched.
