lang/gprolog (probably infinite loop)

[Makoto Fujiwara <makoto%ki.nu@localhost>]

While running bulkbuild (NetBSD/amd64 8.99.42, gcc-7.4.0),, or at the very last stage
of packaging,
lang/gprolog building consumes 99% of CPU after 40H of run.

- I found new version of 1.4.5 instead of current 1.4.4.
  It looks almost the same.

- I've changed to MAKE_JOBS_SAFE = yes and try run again
  with 1.4.5

  The console and top display are as follows:

  |  gplc -c read_file.wam
  |  --- syn_sugar.o ---

  (I'm running MAKE_JOBS= 8)

I suspect gcc problem, so I've tried attache patch as a work around, 
and it packged fine:

Thanks @tristelo for discussion,
