Created attachment 246919 [details] Remove sbrk use in cdrkit and genisoimage The code has fallbacks and when configured with configure presumably used them. Just remove the HAVE_SBRK define from xconfig.h.in to do the right thing. This is untested, but compiles on an amd64 world without sbrk.

Please test thoroughly as my 1 FreeBSD box with a CD is currently not booting... Thanks!
