Macro/enum clash for kpty.h and kprinter.h headers

[Richard Dale]

I'm having trouble with some source code where there is an include 
for 'kpty.h' after an include for 'kprinter.h'. Then the following code tries 
to use the enum PageSize::B0 from kprinter.h and it doesn't compile because 
the 'B0' has been defined as a macro via the kpty.h include.

So should there be an '#if defined(B0) #undef B0' in kpty.h after the 
termios.h include to prevent these two kde headers from interfering with each 
other unpredictably?
