1. MachTen uses PERL_SBRK_VIA_MALLOC and has the same problem with   PERL_POLLUTE_MALLOC as OPENSTEP (see "[ID 19990816.005] Not OK​:   perl 5.00560 on OPENSTEP-Mach 4_2" from Hans Mulder of Mon\, 16   Aug 1999 23​:23​:38 +0200. The attached tweak to Hans' patch   (thanks Hans) applies a band-aid. I agree with Hans that the   current mechanism is broken\, but don't have time to fix it --   holiday beckons. Sorry about that.

2. MachTen's shadow password file support is half-baked\, my patch   extends hints/machten.sh to disable its (attempted) support by   perl.

3. I see the glibc "FAILED at test 192" problem in pragma/warning.   Since MachTen is pretty much unsupported these days\, I don't   hold out much hope of an improved glibc appearing in an official   distribution any time soon\, even after the library's maintainers   have come up with the promised fix. So what are the chances   of coding in a get-out for MachTen and similar sad cases shortly   before perl 5.(​:?00)?6 hits the streets?
