Hmm, it is including the wrong time.h for some reason.

Could you add -v and provide the output, I am mainly looking for the include
patch order.

------- Comment #4 from pinskia at gcc dot gnu dot org  2005-11-21 15:01 -------
We have in libstdc++:
#include <time.h>

So this is invalid. -I does:
       -I dir
           Add the directory dir to the list of directories to be searched
           for header files.  Directories named by -I are searched before the
           standard system include directories.  If the directory dir is a
           standard system include directory, the option is ignored to ensure
           that the default search order for system directories and the spe-
           cial treatment of system headers are not defeated .

either use -iquote which is new for 4.0.0 or use -idirafter

As I said this is invalid.

------- Comment #6 from schnetter at aei dot mpg dot de  2005-11-21 20:53 -------
Thanks for finding the reason.

The include file was actually called "Time.h", but my file system is case
insensitive.
