dmd vs rdmd

[Andrej Mitrovic]

Perhaps -L is just a linux feature, on Windows it only passes options
to Optlink, and passing directories won't add them to search paths for
library files.

E.g. if I have:
main.d
foo/test.d
foo/test.lib <- compiled as a library

and try to invoke:
dmd main.d -I.\foo\ test.lib -L.\foo\

Optlink won't find the lib file:
 Warning 2: File Not Found foo.lib

I always have to specify the full path to the lib file, e.g.:
dmd main.d -I.\test2\ .\test2\foo.lib
