Yes, gdc searchs these files in some standard search paths (the exact details depend on whether you used a sysroot, the --prefix configure option and a few more things). You could implement a DFLAGS like variable with a little known GCC feature, spec files (spec files can read env variables, IIRC): https://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/Spec-Files.html But if you only want to set import paths, we have a D_IMPORT_PATH env variable: https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/d-incpath.cc#L208
