If those attempts fail, it looks for the function in the standard C
library. If any of those methods succeed, it defines

@code{ALLOCA} to @samp{alloca.o} and defines @code{C_ALLOCA} (so
programs can periodically call @samp{alloca(0)} to garbage collect).
This variable is separate from @code{LIBOBJS} so multiple programs can
