kernel object compilation failure unnoticed ?


I updated my sources while the acpi_button.c file was broken (missing
semi-column in r1.32, which was fixed soon after).

I then wanted to compile my own kernel, which succeeded. The
acpi_button.c compilation failed, but the old object remained and
kernel link was ok.

Do anyone else do see such surprising behaviour, where kernel object
file compilation failure remains unnoticed ?

Here follow the build output after removing all acpi* files.
