(I don't like nested includes, and aclocal.m4 should just contain macro 
definitions :-)

Have a look at common/configure.ac.  It's still calling SIM_AC_COMMON 
with a parameter, hence my reason for keeping the SIM_AC_COMMON macro 
(well for at least the moment).

To do like you suggest would mean adding AC_CONFIG_HEADER to 
*/configure.ac (possibly not a bad thing - common/ is probably still 
broken).

Yea, weird :-)

I'll flip the sinclude order.
