HI all :
Factory currenlty has glibc 2.8 which may break some of your packages,
Im going to describe just one possible breakage, and hope someone else
can contribute information about other breakages.
glibc 2.8 no longer defines ARG_MAX constant in linux, so you may see:
foobar.c:N: error: 'ARG_MAX' undeclared (first use in this function)
To fix this problem you can use something like this
#include
