X-Git-Tag: 2.0.4~114
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~mdw/git/mLib/commitdiff_plain/1f85bc74145e009053102f146297a91d9c784f24?hp=5479cb545147d17700fc963cfbd490d7bd96c813

New function allowing an atom's length to be specified at intern time.
Add @ATOM_HASH@ macro so that assoc doesn't have to dig in the @atom@
structure.
