Although it's not good style to simply post to a mailing list without thoroughly browsing the its archives for a similar problem, I'll do it anyway... >:-) To build NHC98 1.12 with a current (= from CVS) GHC, two patches have to be applied: * PrelBase has gone and there are probably *very* few people out there (if any :-) with an ancient GHC <= 2.02, so the lines which make hmake fail can simply be nuked. * Besides other things, -fglasgow-exts switches on the handling of implicit paramters and the syntax %foo for linear implicit parameters. Alas, a space is missing then in LexLow.hs.
