Description Felix Riemann 2005-05-26 14:30:44 UTC 
The file "liux/list.h" is not compatible with C++-code since the function "list_replace_rcu" uses the word "new" as a variable name. C++-code which includes this file fails to compile because "new" is a reserved word in C++.

It can for example be triggered with dev-libs/tvision:

In file included from /usr/include/linux/wait.h:21,
                 from /usr/include/linux/keyboard.h:14,
                 from ../classes/linux/linuxmouse.cc:34:
/usr/include/linux/list.h:222: Fehler: expected `,' or `...' vor "new"
/usr/include/linux/list.h: In function `void list_replace_rcu(list_head*, list_head*)':
/usr/include/linux/list.h:223: Fehler: expected identifier vor

A possible fix would be to change all "new"s in this function to "_new". This would fit to the other functions in list.h which already use this form.

This seems to affect kernel-headers down to version 2.6.9:
