Please take this up with the Cygwin folks on the Cygwin list.  They
deliberately removed this code because the idea is to have Cygwin
builds work like the original program does on Unix and GNU/Linux.  And
MSYS2 follows suit after Cygwin, and AFAIK doesn't have its own port
of Gawk.

I don't think we can apply this patch without an explicit consent on
the part of Cygwin developers.

Thanks.
