Where is builtin_alloca documented?  I can't find it.

Some code (i.e. GNUmake) has code like:
#ifdef  __GNUC__
#define alloca(n)       __builtin_alloca (n)
#else   /* Not GCC.  */

I built gcc V1.34 on a National genix system and it don't know nothin'
about  __builtin_alloca (passes it to the linker which responds with
undefined external messages).

Is __builtin_alloca supposed to be in all gcc compilers (like the sun4
compiler?).
