--- Comment #5 from Dennis Clarke <dclarke at blastwave dot org> 2012-11-12 22:44:19 UTC --- okay, exact same failure happens with -D_POSIX_C_SOURCE=200112L by itself. Am trying with _XOPEN_SOURCE=600 defined. Thus far ( well past 70 secs ) the stage 1 phase seems to be running. So I will report what I see in seven hours or more .. hopefully a lot lot more. dc
