When running cpp -v I do get the following output:
ignoring nonexistent directory "/usr/local/include"
ignoring nonexistent directory "/usr/i386-redhat-linux/include"
#include "..." search starts here:
#include <...> search starts here:
End of search list.
Hm, I do understand why /usr/local/include is here,
but why /usr/i386-redhat-linux/include? Bug?
Oops, must have pressed Commit twice. Closing the second one.
