Hi, I wrote some m4 macros for the boost libraries(see http://randspringer.de/boost/index.html). ATM the default behavior is that the user has to give --with-boost, --with-boost-files-date-time.... to the configure script in order to set the boost compile/linker flags (the last parameter of AC_ARG_WITH sets want_boost="no"). Is there any disadvantage to make the default behavior want_boost="yes" so that user doesn't need to tell anything to configure ?
