Subject: On OS X to use perl's malloc need to USE_PERL_SBRK and emulate sbrk()
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=bc961b003e8925ea1668627dcdfb26c75212b4c6;p=p5sagit%2Fp5-mst-13.2.git

On OS X to use perl's malloc need to USE_PERL_SBRK and emulate sbrk()
using system malloc, because sbrk() stops giving us memory after about
14Mb.
