host: mips-sgi-irix6.2
build: mips-sgi-irix6.2
target: mips-sgi-irix6.2
configured with: /vol/gnu/src/gcc/gcc-3.1-branch-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --enable-languages=c,ada
>Description:
Bootstrapping gcc 3.1 20020502 on IRIX 6.2 (N32 only) succeeds up to the make
bootstrap step.  I've used gcc from GNAT 3.13p as the bootstrap compiler,
bootstrapped itself from the last publicly available IRIX version of GNAT:
gnat-3.11p for mips-sgi-irix5.3.

However, the make gnatlib_and_tools step fails:

../../xgcc -B../../ -c -g -O2   -W -Wall -gnatpg -I. -I/vol/gnu/src/gcc/gcc-3.1-branch-dist/gcc/ada a-chahan.adb
+===========================GNAT BUG DETECTED==============================+

The error persists even without -O2.
	
>How-To-Repeat:
Bootstrap on the target platform and run make gnatlib_and_tools.
