[Click] click cross-compiling question

[Eddie Kohler]

This is not click's <click/algorithm.hh> file, but rather the standard C++ 
<algorithm> header.

Perhaps you did not compile or install target libstdc++ when you built your 
cross compiler?

You can avoid this particular occurrence by not compiling the click tools for 
the target architecture.  Try passing --enable-tools=host to click's configure 
script.
