I got this, the clue is in the definition of sysCallError:
  void sysCallError(DiskEntry *disk, int errno); 
now a quick look over /usr/include/errno.h shows that errno may get defined 
int *__errno __P((void));
#define errno (*__errno())

when it's not already defined, so that expands the prototype to being the 
bizarre thing that it is.

I'm only puzzled why it doesn't show when the code is compiled, perhaps moc's 
cpp isn't that good?  Anyway if you rename that variable to something more 
sane (or in fact remove it from the .h, it doesn't matter there it's only the 
prototype) it should work (busy recompiling kdeutils, I broke it when trying 
to find a solution :)
