* configure.in: rearrange things so that --enable-error-on-warning

Browse source 
uses GUILE_ERROR_ON_WARNING as an indicator and actually set the
value of CFLAGS to include -Werror at the end of configure.in so
it doesn't break any of the non-Werror clean configure tests.
Add check for assert.h since it's used in config.h.in.
