Hi there,
I have a library package which uses AC_CONFIG_HEADERS to create a non-installed generic config.h header as well as an installed header providing (very few) configuration options for the library, with the #define's suitably named (e.g. _LIBFOO_FEATURE_BAZ). My intent is to autoheader-create config.h.in with the generic results and use my self-written libfoo_conf.h.in, therefore I use things like AC_DEFINE([_LIBFOO_FEATURE_BAZ], 1) (or AC_DEFINE_UNQUOTED) for the substitutions, without a third parameter as not to have a template in config.h.in, but define the variable anyway. I feel only defining things once will make the build process less error-prone.
Now current CVS autoheader (2.59a) gives me |autoheader: warning: missing template: _LIBFOO_FEATURE_BAZ |autoheader: Use AC_DEFINE([_LIBFOO_FEATURE_BAZ], [], [Description])
Is this deprecated usage? How is my goal best accomplished? Is having duplicate sets of defines in config.h/libfoo_conf.h the solution of choice? Then I'd suggest the description in info '(autoconf.info)Defining Symbols' to be more precise (where only the usage with one parameter is explicitly discouraged).
You do know about AX_PREFIX_CONFIG_H, do you?
