On cygwin, with D. Korn's proposed patch to cygwin's (i.e., newlib's)
stdio.h, I get a bootstrap failure do to comparison difference(s):

Comparing stages 2 and 3
warning: ./cc1-checksum.o differs
warning: ./cc1obj-checksum.o differs
warning: ./cc1objplus-checksum.o differs
warning: ./cc1plus-checksum.o differs
warning: ./libgcc/_chkstk.o differs
Bootstrap comparison failure!
./ada/exp_aggr.o differs
