Anyway, I'll just switch the recipe to gcc5.

But now I need to fix the gcc5 warnings in the Haiku code :D

For some reason GCC5 doesn't like qe_free() when used with a
pointer-to-void in C++ code:

In file included from haiku.cpp:24:0:
haiku.cpp: In function 'void haiku_close(QEditScreen*)':
qe.h:100:41: error: 'void*' is not a pointer-to-object type
 #define qe_free(pp)    do { typeof(**(pp)) **__ = (pp); (free)(*__);
*__ = NULL; } while (0)

Obviously it tries to create an object of type void. I'm surprised it
actually works in the C code...

There you go, this fixes the Haiku build with gcc5:
- force type in qe_free,
- link to C++ runtime as it's not automatic anymore.
