eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c, ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h, pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c, procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h, strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c, vports.c: Cleaned up use of pairs: Don't make any special assumptions about the internal structure of selectors and mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>), SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc. (Among other things, this change makes it easier to build Guile with certain compilers which have problems with casted lvalues.)
