After Chris's exciting news that my assignment has reached RedHat, here's a

This adds sub-second resolution to the access, modification, and creation
times returned by stat(2) etc. I thought this would make a nice companion to
Corinna's work on making other things in stat(2) be 64-bit.

Also, I was having trouble with a makefile where the commands could execute
in less than a second leading to irregular breakage: this patch fixes that.

I've checked that this maintains both source and binary compatibility (tho'
it does add macros for st_mtime etc. to hide the indirection involved).

I'm unclear whether this is the best naming / type scheme but it is one
recognised by both the make and fileutils packages available from the cygwin
setup (i.e. make this patch and re-compile those packages and they detect
the new fields).

I've provided two separate patches: one for types.h (in the newlib.patch)
and one for the cygwin sources (in winsup.patch). The changelog entries are:


Changelog message:
