-Subject: [PATCH] add support for nommu systems
-
-Rather than hardcode the WIN32 define, add proper fork checks to the
-configure script and check those.  This fixes building for nommu systems
-which lack the fork function.
-
-While we're here though, add support for this functionality via vfork
-so that it does work on nommu systems.  And fix an old bug where we
-exit properly in the forked child when the exec failed instead of just
-returning to the calling code (which isn't expecting it).
