Yes,but if I compile the source with -std=c89 or -ansi, the builtin 
is not defined, then is used  'extern void *alloca (size_t __size)
__THROW;',
which is a normal function define elsewhere ( probably in GNU C
Library... )and called by a normal 'call' procedure.

My question: where is the alloca funtion in the GNU Libc source tree ???
