This is a bug in the code. All functions in glibc can also be macros.
You are messing around with what might be a macro. You'll need to fix
your code to look something like this:

#ifdef __MSDOS__
        printf("%s", a);
#else
        printf("%s", b);
#endif

Or "#undef printf" previous to the broken usage of it, so that you get
the function instead of the macro. The example I gave is more readable,
so I suggest it.
