I get these errors with terminal.d (on OSX):

Joels-MacBook-Pro:small joelcnz$ rdmd term.d
arsd/terminal.d(1268): Error: undefined identifier 'SIGWINCH'
arsd/terminal.d(1381): Error: undefined identifier 'SIGWINCH'
Joels-MacBook-Pro:small joelcnz$

Note: I've got term.d as the main file, I've got terminal.d in 
arsd folder

I've put up an issue on your github site.
