A simple test app that reproduces this issue:
#include <google/sparse_hash_set>
int main() {
}
The problem seems to be that g++-4.3 puts hash_fun.h in a different
location from g++-4.1 and g++-4.2. Sparsehash uses whatever the location
was for the default compiler at the time it was built. So a build on a
system with g++-4.3 as the default compiler will produce a header that
fails with g++-4.1 and g++-4.2 and a build on a system with g++-4.1 or
g++-4.2 as the default compiler will produce a header that fails with
g++-4.3.
This issue affects lenny squeeze and sid.
A patch is attatched that makes the package produce a header that builds
with 4.1, 4.2 and 4.3
