Hi Paul, > (I did reproduce the bug). Have you reproduced the warning "AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS" with autoconf 2.63 but not 2.64 ? I'm asking because when I added that comment on 2009-01-25, the newest released version at that moment was 2.63. So, unless you have verified otherwise, it could very well be that this warning is still present with newer versions. Bruno
