My understanding is that it is re-generated at each stage: auto-host.h: cstamp-h ; @true cstamp-h: config.in config.status CONFIG_HEADERS=auto-host.h:config.in \ CONFIG_FILES= \ LANGUAGES="$(CONFIG_LANGUAGES)" $(SHELL) config.status In case this can make a difference, the compiler is configured as follows: --enable-languages=c,ada,c++ --disable-libada --enable-checking=release -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38591
