RSB builds single-threaded Newlib by default?

[Linda Huxley]

Hi Chris,

I am still unable to build the RTEMS kernel. ...cpukit/configure fails 
because the following check returns a negative response:

checking for struct _Thread_queue_Queue._name... no

The configure script is searching sys/lock.h for a structure member. 
sys/lock.h appears here in my build tree:

/c/opt/rtems/r4.11.2/sparc-rtems4.11/include/sys/lock.h

However, that version of lock.h only contains "dummy lock routines for 
single-threaded aps".  I have attached a copy of sys/lock.h.

Is there some build setting or environment variable that I have to set 
to build a multi-threaded version of newlib?

Thanks,

Linda
