Which one is better ? AS_IF is nicer if you invoke other autoconf macros within the body, because it handles hoisting prerequisites prior to the if statement. In other words: if ...; then MACRO_WITH_PREREQ fi => if ... prereq macro_body fi which is a bug, if the rest of your script depends on prereq having run regardless of whether macro_body was run (and that is often the case). On the other hand, AS_IF([...], [MACRO_WITH_PREREQ]) => prereq if ... macro_body fi - -- Don't work too hard, make some time for fun as well!
