Why? Functionally, all you need to know is whether a symbol is declared within a set of headers, rather than trying to go the extra mile to figure out which exact header. So for this particular case, I would have used something like: AC_CHECK_DECLS([bzero],[],[],[AC_INCLUDES_DEFAULT [#include <string.h> #ifdef HAVE_STRINGS_H # include <strings.h> #endif ]]) to find whether bzero is declared in either string.h or strings.h, then include both headers in my code. But ultimately, bzero is declared obsolete by POSIX. If you REALLY want to be portable, I'd write your code to use memset and not bzero. - -- Don't work too hard, make some time for fun as well!
