Not enough apparently. :-)  I get this on x86-64/Linux:

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
gcc.o(.text+0x128): In function `issue_strict_overflow_warning':
/home/eric/svn/gcc-4_2-branch/gcc/flags.h:347: undefined reference to
