Subject: $Config{sig_num_init}.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=824a2ba35a8a435c7dda7b79d43bec16c40e4bd9;p=p5sagit%2Fp5-mst-13.2.git

$Config{sig_num_init}.
Also, a new approach to the 'pthreads-created-joinable': drop
it and use {PTHREAD_CREATE_{JOINABLE,UNDETACHED},__UNDETACHED}
directly. (See also #2096).
