| Subject: In forked children, set SIGPIPE to SIG_DFL. |
| |
| --- |
| * io.c (two_way_open): In forked child, reset SIGPIPE to SIG_DFL. |
| Fixes problems with "broken pipe" errors from child processes, |
| restoring 4.1.0 and earlier behavior. Thanks to Daryl F |
| <wyatt@prairieturtle.ca> for the report. |
| (gawk_popen): Ditto. |
