access() is not your friend... this reminds me of

memory: avoid a name clash with access macro
This avoids a name clash with the access macro on windows 64:
make
CHK version_gen.h
CC aarch64-softmmu/memory.o
/home/konrad/qemu/memory.c: In function 'access_with_adjusted_size':
/home/konrad/qemu/memory.c:591:73: error: macro "access" passed 7
arguments, \
but takes just 2
(size - access_size - i) * 8, access_mask, attrs);
