The problem isn't one of syntax (you can have headers without the .h
in C as well), but rather that makedepend doesn't know the proper
include path for C++.  All the C++ compilers I've ever seen have their
own directory of C++-only include files and pass the preprocessor (if
it's a separate program) the necessary options to look there as well.

So, you should check the documentation for your C++ compiler to see
what other paths it uses or otherwise how to have it show you the
paths that it uses.  Then, add -I options to your makedepend macro so
it looks there too.
