I used the DIST OPTIONS thing to enable all sub packages for
distribution.  See my links below for how I did it (hopefully I chose
a method that's ok)

Well, I committed it to svn, so everything is available here:
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/trunk/Makefile.am?view=markup
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/trunk/configure.ac?view=markup

Previously, in the case statements, I had AC_CONFIG_SUBDIRS in each
path.  For instance:

[yes|all],[
   with_libraries="libmangle,pseh"
   with_libraries_mangle=yes
   with_libraries_pseh=yes
   AC_CONFIG_SUBDIRS([mingw-w64-headers/libraries/libmangle])
   AC_CONFIG_SUBDIRS([mingw-w64-headers/libraries/pseh])],
[libmangle],[
   with_libraries="libmangle"
   with_libraries_mangle=yes
   with_libraries_pseh=no
   AC_CONFIG_SUBDIRS([mingw-w64-headers/libraries/libmangle])],
...etc

That tossed an error saying that the directory libmangle was already
in the list of stuff to be configured.
