make: Fatal error: Command failed for target `bootstrap'

No, I'm not building gcc in the source directory.  After the
failure, I did a "make bootstrap >> build.log" and it
finished, including lines like
make[4]: Entering directory `/export/home/lucier/gcc/gcc-3.1/objdir/sparc-sun-solaris2.8/libstdc++-v3/include'
sed -e '/^#/s/\([ABCDEFGHIJKLMNOPQRSTUVWXYZ_][ABCDEFGHIJKLMNOPQRSTUVWXYZ_]*\)/_GLIBCPP_\1/g' \

Is there a problem that the sparc-sun-solaris2.8/bits/
directory was not yet built the first time gthr.h was
(almost) built?  Is there a dependency problem here?
