On IRC Marius mentioned this bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129#c3 Note that we use C_INCLUDE_PATH, which is equivalent to ‘-isystem’. Quoth (gnu packages gcc): (native-search-paths ;; Use the language-specific variables rather than 'CPATH' because they ;; are equivalent to '-isystem' whereas 'CPATH' is equivalent to '-I'. ;; The intent is to allow headers that are in the search path to be ;; treated as "system headers" (headers exempt from warnings) just like ;; the typical /usr/include headers on an FHS system. (list (search-path-specification (variable "C_INCLUDE_PATH") (files '("include"))) (search-path-specification (variable "CPLUS_INCLUDE_PATH") (files '("include"))) (search-path-specification (variable "LIBRARY_PATH") (files '("lib" "lib64"))))) Ludo’.
