>Description:
Current mainline CVS version GCC can't be compiled at FreeBSD after next GCC version changed from 3.5 to 4.0.

Header /usr/include/sys/cdefs.h:136 have invalide version check:

#if __GNUC__ == 2 && __GNUC_MINOR__ >= 7 || __GNUC__ == 3

That make __dead undefined and break compiletion of GCC at stdlib.h header wher __dead used.


>How-To-Repeat:

>Fix:
Modify affected line by 

#if __GNUC__ == 2 && __GNUC_MINOR__ >= 7 || __GNUC__ >= 3
