Hi, maybe this is some fallout from the toplevel-bootstrap patch...
I configured current mainline with $SRCDIR/configure --quiet --prefix=$DESTDIR --enable-languages=c++,fortran --with-gmp=/usr/local/appl/gmp-4.1.4 --enable-checking=release and the bootstrap stopped at make[2]: Entering directory `/scratch/ogcc/stagefeedback-libcpp' gcc -I/scratch/gcc/libcpp -I. -I/scratch/gcc/libcpp/../include -I/scratch/gcc/libcpp/include -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -pedantic -Wno-long-long -Werror -I/scratch/gcc/libcpp -I. -I/scratch/gcc/libcpp/../include -I/scratch/gcc/libcpp/include -c -o charset.o -MT charset.o -MD -MP -MF .deps/charset.Po /scratch/gcc/libcpp/charset.c cc1: warnings being treated as errors /scratch/gcc/libcpp/charset.c:1: warning: 'charset.gcda' is version '402e', expected version '400*' make[2]: *** [charset.o] Error 1 make[2]: Leaving directory `/scratch/ogcc/stagefeedback-libcpp' make[1]: *** [install-libcpp] Error 2 make[1]: Leaving directory `/scratch/ogcc' make: *** [install] Error 2 I observed this on i686 and x86_64.
