+You must build and install the pcc-libs module which contains libpcc.a and stddef.h header files.
+
+The alloca.h glibc header file is broken so alloca() doesn't work.  The header file undefines alloca and then fails to set it to something useful if _GNUC_ is not defined.
+
+Try putting the followign into /usr/local/include/pcc/alloca.h:
+
+#ifndef _ALLOCA_H
+#define _ALLOCA_H
+
+#include <features.h>
+
+#define __need_size_t
+#include <stddef.h>
+
+__BEGIN_DECLS
+
+/* Remove any previous definitions.  */
+#undef  alloca
+
+/* Allocate a block that will be freed when the calling function exits.  */
+extern void *alloca (size_t __size) __THROW;
+
+#if defined(__GNUC__) || defined(__PCC__)
+# define alloca(size)   __builtin_alloca (size)
+#endif /* GCC.  */
+
+__END_DECLS
