Alloca configure test fails

           Summary: Alloca configure test fails

On x86 Linux at least, alloca is not in libc, it's strictly a compiler 
builtin function. You test for with with the AC_CHECK_FUNCS macro which does 
its work by trying to use the address of the function. I've tried a number 
of different versions and they all seem to decide that you can't want the 
builtin function because you're using an address so they emit a normal 
external symbol. Of course, this fails with a linker error.

I think you need a different test if you're using gcc.
