(-std=c99 -pedantic)
Of course, one can't use -std=c99, because not everyone has gcc 4.x. So, the problem is still there. And even -std=gnu99 -pedantic doesn't solve the problem since there are other spurious warnings (for code enabled by the preprocessor if the compiler is gcc). Now I think that this can be dealt with by making the configure.in even more complex. :( -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / Arenaire project (LIP, ENS-Lyon)
