Because your toolchain is broken?  (Most likely your header files?)

Do your header files have toupper and tolower declared as inline functions in 
the header, without being declared static so it doesn't output assembly 
versions of them (just in case somebody takes the address of the function)?

Fire up the gcc man page and look for -fkeep-inline-functions for more info.

I note that building busybox 1.3.2 with the gcc 4.3.2 in Ubuntu 8.10 works 
fine for me on x86_64.
