something goes wrong:

gcc   -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute
-fno-common   -DHAVE_CONFIG_H  -o xgcc gcc.o opts-common.o
gcc-options.o gccspec.o \
 intl.o prefix.o version.o driver-i386.o  ../libcpp/libcpp.a
../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -lmpfr -lgmp
gcc.o: In function `issue_strict_overflow_warning':
../../gcc/gcc/flags.h:342: undefined reference to `warn_strict_overflow'
collect2: ld returned 1 exit status
make[3]: *** [xgcc] Error 1

I guess the -fkeep-inline-functions is the culprit (the code seems to rely on
flags.h:issue_strict_overflow_warning function being removed).  Bootstrap
compiler is gcc 3.3.3-hammer for me.
