displaying the expected type. Use SCM_LISTn in a couple places instead of scm_cons-ing by hand. * __scm.h: Added SCM_ASSERT_TYPE macro. * validate.h, scm_validate.h: Added the former, as a renamed version of the latter with SCM_ASSERT_TYPE used in SCM_MAKE_VALIDATE (instead of just SCM_ASSERT) * Makefile.am: Rename scm_validate.h to validate.h. * *.c, *.h: Include validate.h, not scm_validate.h (old name's prefix was superfluous).
