Hi, Is there a way to produce a header file at configure time using AC_CONFIG_HEADERS, *and* have it perform AC_SUBST-itutions on the files, like AC_CONFIG_FILES? What I'd like is AC_CONFIG_FILES to also perform a difference check on the output files before overwriting them, just the way AC_CONFIG_HEADERS does. (Is this a safe and easy request to accommodate?) In my case, these output files are headers at the leaves of deep dependency-chains (not all C/C++). I basically do NOT want to AC_DEFINE such variables because they will end up changing config.h -- I'd rather have these variables isolated from config.h. Another idea could be to provide an option in AC_DEFINE to retarget to another file besides the default "config.h"? Any ideas?
