It might additionally add multilib path variants (/usr/include/d/32). (In practice it's more complicated to also support 'relocated' compilers. GCC remembers the full path at compilation time but if you move the gdc executable it will replace the paths prefix.

I have seen Can't you just use --prefix when configuring? Ore use -I or the D_IMPORT_PATH environment variable? Anyway, the code you'll have to look at is here: https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/d-incpath.cc Look at add_import_paths, called from d_init in d-lang.cc > https://github.com/Dicebot/Arch-PKGBUILDs/blob/master/gdc/folders.diff > and followed that example, but of course changing configure.ac is a > pain because then you have to have exactly the right version of > autoconf to update configure.

Does DMD print the import path for these errors?
