Thanks for testing. I had looked into the make problem further, and found this was not caused by the errno overwriting, but by calling sig_dispatch_pending() in fixup_after_exec() via kill(). fixup_after_exec() is called from dll_crt0_0(). It seems that calling sig_dispatch_pending() from dll_crl0_0() causes hangs everywhere (even outside PTY). I am not sure what exactly does sig_dispatch_pending() and why this causes the problem, anyway, using pinfo() rather than kill() solves the issue.
