Hmm, is this supposed to be true for C++ as well?

Recently I tried to do an incremental build of the llvm+clang tree
after switching to gcc as a compiler, from the system's installed
clang (which was having problems at the time, thus the switch).  The
resulting incremental build started spewing out link errors at some
point... which a "make clean" and rebuild fixed.

[However "switching to gcc" involved re-running configure, so the
problems may have been due to some difference in the autoconf-set
parameters...]

Thanks,
