gnat with gcc 3.1 build failure

gnat with gcc 3.1 build failure

[Joel Sherrill]

HI,

I am trying to build gnat targetting sparc-rtems.  This 
is a well tested target on the gcc 2.8.1 based gnat 
versions.  My environment is:

Host: GNU/Linux RedHat 7.2
Native GNAT: ACT binaries 3.14p from cs.nyu.edu
GCC Version: 3.1-20010423

Build steps:

threads="--enable-threads=rtems"
prefix=/opt/gcc-3.1-test
t=sparc-rtems
../gcc-3.1-20020423/configure --target=${t} \
     ${threads} --prefix=${prefix} \
    --with-gnu-as --with-gnu-ld --with-newlib --verbose \
    '--enable-languages=c,ada' && \
make && \
cd gcc && \
make cross-gnattools && \
make ada.all.cross && \
make CC=gcc GNATLIBCFLAGS="-O2 -g" gnatlib

The failure is during "make cross-gnattools"

gcc -c -g -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wtraditional    -W -Wall -gnatpg -gnata -I- -I.
-I../../../gcc-3.1-20020423/gcc/ada
../../../gcc-3.1-20020423/gcc/ada/s-imgrea.adb
s-imgrea.adb:508:15: expected an access type with designated type
"System.Fat_Gen.T" from instance at s-fatllf.ads:49
s-imgrea.adb:508:15: found type "System.Address"
make[2]: *** [s-imgrea.o] Error 1

Suggestions (and patches :) appreciated. 

Thanks.
