Hm, the only of these 4 macros used in g032-nat.c is FP0_REGNUM. I don't see any
other definition of FP0_REGNUM beside the one in gdbarch.h

#if !defined (GDB_TM_FILE) && defined (FP0_REGNUM)
#error "Non multi-arch definition of FP0_REGNUM"
#endif
#if !defined (FP0_REGNUM)
#define FP0_REGNUM (gdbarch_fp0_regnum (current_gdbarch))
#endif

So go32-nat.c uses gdbarch_fp0_regnum, doesn't it? What am I overseeing?
Thank you very much for your review.
