CVS questions

[Rasmus Tamstorf <rt brandx net>]

When I build glib and gtk from a fresh cvs checkout I get a lot of :

  warning: AC_TRY_RUN called without default to allow cross compiling

What is the deeper meaning of that ? 

Also, when you checkout a project with cvs you can specify which branch
you want, but how do you know what branches are available ? Is there a
'ls' or 'dir' command or maybe 'info' ?
