Just to clarify: For LDC, -L-L$PREFIX/include/d _is_ included in 
the default configuration file, but the compiler doesn't 
automatically add the path internally.

The reason for this is simple: In some situations, you do _not_ 
want your compiler to go looking in some hard-coded directory, so 
we would have to add an extra switch to disable that behavior. 
And with two versions of D being around, and $PREFIX often being 
what a D1/Tango installation defaults to as well, those 
situations aren't as uncommon as one might think at first.
