[Libsysio-commit] HEAD: libsysio/src stat.c

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1:/tmp/cvs-serv4984/src

Modified Files:
	stat.c 
Log Message:


A struct stat and a struct sts64 don't quite match up with the field offsets.
I had thought otherwise. Now, we convert between the two.
