Okay, checking my source code:

landley at driftwood:~/busybox/busybox$ find . -name "*.h" | xargs grep sigval
landley at driftwood:~/busybox/busybox$  

None of our .h files include the string "sigval", so we can't be defining it 
twice.  The problem has to be the headers in your build environment.  I'd 
guess they don't have the standard #ifndef/#define/#endif guards around them 
to prevent bad things from happening when they're included twice.  (Which, 
since header files include other header files, is unavoidable.  Hence the 
invention of the guards over 30 years ago.)

I.E. This is not busybox's problem.  Your build environment is defective.  (We 
may be other problems, but since they occurred after the first one in your 
list we can't tell due to the fallout and shrapnel...)
