There was a bug that I found in gcc 4.6 (now fixed) which caused any program that used glibc + -O3 + strcmp to give a warning, which would cause it to fail to compile with -Werror. However developers themselves should definitely be using compiler warnings and fixing them. In libguestfs we have some pretty complex autotools magic to deal with all this: http://git.annexia.org/?p=libguestfs.git;a=blob;f=configure.ac;h=f1b56d2dbe9a118901f7426bcc176f624d841f63;hb=HEAD#l67 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.
