Summary: sizeof applied to an incomplete type gives 0

Initial Comment:
Hi.

That looks like a bug that sdcc eats the code like
this, compiling the "sizeof" as zero:
---
#include <string.h>

struct {
char a;
short b;
} test;

char main() {
  memset(&test, 0, sizeof(struct test));
  return test.a;
}
---

This is how gcc handles that:
$ gcc struct.c 
struct.c: In function `main':
struct.c:9: sizeof applied to an incomplete type

Perfect error message above, but sdcc just compiles
the broken code for that example. Could it please also
print an error message instead, the way gcc does?
The example is attached.
