Why? 2.2 have installed thesrc over the 2.1.5R sources wrong. The ``Holzhammer-Methode''. :-) Of course, you haven't fixed anything, except that you've now lowered the warning level that is in effect for the kernel compilation. There are thousands of comparisions of signed with unsigned in the code, unfortunately. Starting with version 2.7, gcc now complains about this if some warning level is in effect (-W i think). It's a non-trivial task to fix all of them, since somebody has to walk the entire tree. Most of them arise out of two or three nested typedefs. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
