unable to build head on Fedora


My fresh check out on the head build using the gcc shipped with
Fedora Core 4 has failed for the past couple of days with this error:

/home/joel/gcc-work/head/b-native/./gcc/xgcc -B/home/joel/gcc-work/head/b-native/./gcc/ -B/home/joel/gcc-head-test//i686-pc-linux-gnu/bin/ -B/home/joel/gcc-head-test//i686-pc-linux-gnu/lib/ -isystem /home/joel/gcc-head-test//i686-pc-linux-gnu/include -isystem /home/joel/gcc-head-test//i686-pc-linux-gnu/sys-include -c -g -O2 -fPIC -W -Wall -gnatpg g-alleve.adb -o g-alleve.o
