X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=4181e3555d644327354a2dc20295251d01e07f2b;p=p5sagit%2Fp5-mst-13.2.git

Anton Berezin says that on FreeBSD we're wrong to be using -lc_r, and
should just be using -pthread on the linker line.
This stops the new taint tests looping infinitely. It also seems to
cure the TODO test in posix.t - masked SIGINT is now received.
