[Qemu-devel] new code_copy code gives: error: storage size of `ldt' isn't known in helper2.c:97

[Martin]

Until recently I was able to build qemu-cvs but I updated today and now 
it gives an error:
/pub/projects/emulators/qemu/qemu-0.5.3-cvs/qemu/target-i386/helper2.c: 
In function `cpu_x86_init':
/pub/projects/emulators/qemu/qemu-0.5.3-cvs/qemu/target-i386/helper2.c:97: 
error: storage size of `ldt' isn't known
The problem is in the new code_copy code
helper2.c:94:
#ifdef USE_CODE_COPY
   /* testing code for code copy case */
   {
       struct modify_ldt_ldt_s ldt; //This is line 97

in target-i386/syscall.h the struct modify_ldt_ldt_s is defined:
target-i386/syscall.h:32:
struct target_modify_ldt_ldt_s {
   unsigned int  entry_number;
   target_ulong base_addr;
   unsigned int limit;
   unsigned int flags;
};

I can't see what the problem is.
Does anybody know?
Greetings,
Martin
