problem with using rdbg on i386 target

[Eugene Denisov]

Hello.

I'm trying to use remote debugging of i386-pc target via 
ethernet and get the following problem:

As I understand I need to compile gdb-5.2 with applied patches 
from current RTEMS release (4.6.0pre5) with 
--target=i386-RTEMS

unfortunately it fail to compile with this target (however it 
successfully compiles for i386-rtems target):

$ ../gdb-5.2/configure --prefix=/opt/rtems-gdb 
--target=i386-RTEMS
Configuring for a i686-pc-linux-gnu host.
Invalid configuration `i386-RTEMS': system `RTEMS' not 
recognized
Unrecognized target system name i386-RTEMS.

I attempted to modify configure scripts but get no success.

Please help me.

Best regards,
Eugene Denisov
