gcc4.0.2/newlib1.14.0 build failure for i386-rtems target

[Brian Rose]

So have you successfully used gcc-4.0.2 to build rtems? I tried several 
months ago and found that rtems would not build because the rtems code 
contains some macros and other constructs that are considered errors in the 
newer compiler.

Thanks,
