Compiling Derelict3 https://github.com/aldacron/Derelict3 with dmd/druntime/phobos from github, I got this error: [...] ../import/derelict/opengl3/glx.d(177): Error: expected 3 function arguments, not 2 [...] It seems a regression, in that it's ignoring default arguments. No problem with dmd 2.059 Regards, -- Jordi Sayol
