Gosh, commenting it out is a poor way to solve the problem, why not just
find out the cause ?????  The message the compiler gave is quite clear,
it points out an error in the pointer assignment, obviously the return
type from your signal() function doesn't jibe with whatever bgnd_flag is.
I'll bet dollars to donuts your signal returns void and bgnd_flag is an int.

As for your other problem, just commenting out the text after the #else
or #endif will solve that problem.  That error doesn't stop the compile
anyway, it's just informational and clutters up the screen.
