In theory the code at the start of ldgram.c should take care of this:

  #ifndef alloca
  #ifdef __GNUC__
  #define alloca __builtin_alloca
  #else /* not GNU C.  */
  #if (!defined (__STDC__) && defined (sparc)) || defined (__sparc__) || defined (__sparc) || defined (__sgi)
  #include <alloca.h>
  #else /* not sparc */
  #if defined (MSDOS) && !defined (__TURBOC__)
  #include <malloc.h>
  #else /* not MSDOS, or __TURBOC__ */
  #if defined(_AIX)
  #include <malloc.h>
   #pragma alloca
  #else /* not MSDOS, __TURBOC__, or _AIX */
  #ifdef __hpux
  #ifdef __cplusplus
  extern "C" {
  void *alloca (unsigned int);
  };
  #else /* not __cplusplus */
  void *alloca ();
  #endif /* not __cplusplus */
  #endif /* __hpux */
  #endif /* not _AIX */
  #endif /* not MSDOS, or __TURBOC__ */
  #endif /* not sparc.  */
  #endif /* not GNU C.  */
  #endif /* alloca not defined.  */
  
Is <alloca.h> being included ?  If not then perhaps it needs to be.

Alternatively if you add "+Olibcalls" to the aCC command line, does
the link complete ?

Cheers
