I just deployed 0.12.2-2 as test.  Apart from setproctitle{_init}, it
also drops exporting the following symbols already exported from Cygwin:

    arc4random*
    explicit_bzero
    fpurge
    getprogname
    reallocarray
    reallocf
    setprogname
    strlcat
    strlcpy
    strnstr
    wcslcat
    wcslcpy

Given cygbsd-0.dll still defines these functions, it should still work
with older executables.


Thanks,
Corinna
