The problem shown below is the result of defining "unsigned long flags" in the middle of the function. Older GCC compilers always want the data declarations to precede any code.

Busybox build was invoked like this:
make CFLAGS_EXTRA="-mtune=arm7tdmi -O2" LDFLAGS="-Wl,-elf2flt"
The attached patch fixes the problem.
