Submitted by: Kevin P. Fleming (kpfleming at cox dot net) Date: 2003-09-12 Initial Package Version: 2.6.0-test5 Origin: Kevin P. Fleming (kpfleming at cox dot net) Description: The definition of __invalid_size_argument_for_IOC is signed, which causes an signed/unsigned comparison error to be emitted by GCC (at least for 3.3.1).
