Description Eric Botcazou 2011-02-10 13:33:07 UTC 
The error message for a missing argument to -I has disappeared.  It used to be:

gcc: argument to '-I' is missing

Now a cryptic message is issued:

cc1: fatal error: /home/eric/build/gcc/native32/gcc/../lib/gcc/i586-suse-linux/4.6.0/: No such file or directory
compilation terminated.

As a matter of fact, the Ada compiler is also affected.

This was for an uninstalled compiler.  For an installed one:

cc1: warning: t.c: not a directory [enabled by default]

and the compiler waits indefinitely.
