2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
* numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
SCM_UNPACK / SCM2PTR correctly.
2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (adjust_gc_trigger): Improved documentation.
