Make the rule for .hi files depend on the .hs/.lhs files

make thought that it could make a .hi file for the C files in libraries, which was causing problems when using dynamic-too.

Are you sure? This rule is *very* delicate (see the comments). Won't this change cause make to think that it can build the .hi file by not doing anything?

I hesitate to say I'm sure, but I don't see the problem. The old rule was roughly: %.hi: %.o ; and I could break the change into 2 parts, first changing it to something like: a/%.hi: a/%.o ; and then to something like: a/%.hi: a/%.o b/%.hs ; Which step do you think is wrong, and why?

...

+define hi-rule # $1 = source directory, $2 = object directory, $3 = way

-%.$$($1_hisuf) : %.$$($1_osuf) ; +$2/%.$$($3_hisuf) : $2/%.$$($3_osuf) $1/%.hs ;

Thanks Ian
