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
