Ok, I think I found one reason for this:
e.g.:
cc: "calc.c", line 117: error 1000: Unexpected symbol: "}".
cc: "calc.c", line 128: warning 23: Semicolon required after last member.
cc: "calc.c", line 128: warning 500: Unnamed struct/union members are ignored.
cc: "calc.c", line 114: error 1613: Zero-sized struct.

If I change the file to:
#ifndef YYLTYPE
typedef struct yyltype
{
  char dummy;
} yyltype;
# define YYLTYPE yyltype
# define YYLTYPE_IS_TRIVIAL 1
#endif

[dummy added]
This will compile.
