Compile error in SMP / IO-Apic code

The bug affects 2.4.19-ac1 and -ac2 but not 2.4.19-rc3 (my running kernel.) 
Also, both gcc 2.95 and 3.0 fail to compile the affected file.

The text of the compiler failure follows:

gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe
