* sysdeps/stub_suid: New directory. This is mainly used as example
for people porting libgtop to other systems.
* glibtop.h (_glibtop): New fields `error_method', `sysdeps' and * glibtop.h (_glibtop): New fields `error_method', `sysdeps' and
`required'. I added an improved error handling: the client can tell `required'. I added an improved error handling: the client can tell
the libraries which fields are absolutely required for each features the libraries which fields are absolutely required for each features
