Case consistency of #include files

[EricBracken]

This is not a bug; it's an enhancement request. Would it be possible to check for inconsistency in the case of file names in #include statements, so that attempting to include myfile.h with #include "MyFile.h" would throw a warning?

This would be a big help for people developing on (say) Windows, where the case doesn't matter, who want to port their code to Linux.
