[cvs-nhc98] patch applied (hat): Multiple definitions of a CAF should be an error.

Tue Nov 13 06:01:06 PST 2001 malcolm * Multiple definitions of a CAF should be an error. This fix, when grouping function clauses together, ensures that separate clauses of a CAF are never grouped. Hence, the multiple definition can be detected later. M ./src/compiler98/Rename.hs -8 +9
