You get:

gcc -c -I.  -g -Bstatic expread.tab.c
/usr/include/alloca.h:3: warning: alloca redefined
mv expread.tab.o expread.o

This is fixable as follows:

diff -c -r1.1 defs.h
*** /tmp/,RCSt1a12229   Mon May 21 17:11:09 1990
--- defs.h      Thu May 17 10:59:11 1990

  extern char *reg_names[];

  /* Various possibilities for alloca.  */
- #ifdef __GNUC__
- #define alloca __builtin_alloca
- #else
  #ifdef sparc
  #include <alloca.h>
  #else
  extern char *alloca ();
  #endif
