Yes, please. Since you are at HP, you at in a very good position for
reporting these three HP-UX 10.20 cc bugs to HP.

=========================== bug1.c ========================
#include <stddef.h>
enum {
  a = offsetof(struct { char x; long y; }, y)
};
enum {
  b = a
};
===========================================================

$ cc -Ae -c bug1.c
cc: "bug1.c", line 6: error 1509: Enumeration value must be constant.

Bug the enumeration value in line 6, namely "a", is a constant, according
to ISO C 99 section 6.6.(6). {I'm not joking!}

=========================== bug2.c ========================
#include <stddef.h>
enum {
  a = offsetof(struct { char x; long y; }, y)
};
int b = a;
===========================================================

$ cc -Ae -c bug2.c
cc: "bug2.c", line 5: error 1521: Incorrect initialization.

=========================== bug3.c ========================
#include <stddef.h>
#include <stdio.h>
enum {
  a = offsetof(struct { char x; long y; }, y)
};
int main () { printf("%d", a); return 0; }
===========================================================

$ cc -Ae -c bug3.c
cc: line 6: main(): internal error 5167: Alignment inappropriate for Ucode 
operator (5167)

Uh uh, cc caught itself...

I'll add a workaround to the next gettext release. Thanks for the report.
