Did you try using the version of gcc for SCO at:

I was just about to ding you with an RTFM answer, but it looks like you
DID do the right thing and the tools did the wrong thing bechind your back.

Somehow, either 
  A) cpphash is using alloca when it shouldn't or 
  B) this code is being built with the "wrong" compiler - /bin/cc doesn't
     have alloca bug GCC does have this as an extension that's turned on 
     by default.
  C) you configured with one compiler (gcc-ish) and built with 
     another (/bin/cc) which is, I suppose, a variation of "B".

What does the following command return on your system?

$ grep -i alloca config.cache ; grep ALLOC gcc/auto-host.h
ac_cv_func_alloca_works=${ac_cv_func_alloca_works='no'}
ac_cv_header_alloca_h=${ac_cv_header_alloca_h='no'}
#define C_ALLOCA 1
/* #undef HAVE_ALLOCA */
/* #undef HAVE_ALLOCA_H */
#define HAVE_MALLOC_H 1
#define HAVE_DECL_MALLOC 1
#define HAVE_DECL_REALLOC 1
#define HAVE_DECL_CALLOC 1
