[Bug: 21.5-b31] Sub-process fails in ginger/Cygwin native

================================================================ Dear Bug Team! I recently built ginger from source, no problems with build process, but subprocess forking fails. For instance, if I do M-x shell, I get Process sh background write attempted from control tty Poking around a bit I see this is a signal -- happy to try to narrow this down if someone can give me suggestions where to look. . . I'm running latest Cygwin (1.7.9-1) on Windows 7 Ultimate Pro. This problem does not occur with a build of 21.5-b29 that I did in December. ht ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-6.1-WOW64 kung 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin ./configure '--with-pdump=yes' '--with-modules=no' '--with-mule=yes' '--with-ncurses=yes' '--with-msw=yes' '--with-png' '--with-xpm' '--with-jpeg' '--with-database=berkdb,gdbm' XEmacs 21.5-b31 "ginger" c5fde3f37fef configured for `i686-pc-cygwin'.
