--- Comment #11 from Thomas Schwinge <tschwinge at gcc dot gnu.org> --- (In reply to myself from comment #10) > Could we easily build a portable 'flock'-like using 'fcntl' locking > primitives? (<https://www.perkin.org.uk/posts/solaris-portability-flock.html>, for example.) > (I've not yet looked.) But simpler, is it OK to require Perl (Ick!) for parallelized 'check-target-libgomp'? There's <https://perldoc.perl.org/functions/flock>, and I've got that implemented as a fallback 'flock'. (It's certainly not, after two decades or so, my desire to write something in Perl, but I suppose it's available "almost everywhere" and the fallback 'flock' is simple to implement.)
