Odd. Unlike on /lib/gcc/i686-apple-darwin10/4.2.1/libgcov.a, nm on /usr//lib/gcc/i686-apple-darwin10/4.0.1/libgcov.a does not reveal any reference on the missing symbols.
nm /usr/lib/gcc/i686-apple-darwin10/4.2.1/libgcov.a | grep vproc
U _vproc_transaction_begin
U _vproc_transaction_end
nm /usr/lib/gcc/i686-apple-darwin10/4.0.1/libgcov.a | grep vproc
(nothing)
