* libguile/_scm.h: Remove gc.h. * libguile/arrays.h: * libguile/bytevectors.h: * libguile/foreign.h: * libguile/fports.h: * libguile/frames.h: * libguile/hashtab.h: * libguile/modules.h: * libguile/numbers.h: * libguile/print.h: * libguile/programs.h: * libguile/smob.h: * libguile/snarf.h: * libguile/strports.h: * libguile/struct.h: * libguile/symbols.h: * libguile/variable.h: * libguile/vectors.h: * libguile/vm.h: Add gc.h to users of scm_cell_* interfaces. Not really visible right now given that e.g. numbers.h is already included in _scm.h.
