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.

Thanks.
