Diego, is there a way to switch that off? No, not really.. -Wimplicit-function-declaration and autoconf don't get along together. a) -Werror is the only way to catch if the attributes work at all as often enough they just emit warnings; b) AC_CHECK_LIB/AC_SEARCH_LIB will also fail with -Werror=implicit-function-declaration so if the two are combined will be a problem. But really it would be simpler if somebody picked up unieject upstream at this point, I haven't worked on it for way too long. I am using that flag to catch flags mixtures as a C-only FLAG. Which other would you suggest? http://blog.flameeyes.eu/2008/08/06/flags-and-flags I have some code out there to implement that kind of testing in non-disruptive ways.

I only knew your other with the flagcheck.h. Thanks again. |
