Remove the definitions of the following: acl, aclcheck, aclfrommode,
aclfrompbits, aclfromtext, aclsort, acltomode, acltopbits, acltotext,
chown, fchown, _fcntl, fstat, _fstat_r, ftruncate, getegid, geteuid, getgid,
getgrent, getgrgid, getgrnam, getgroups, getpwduid, getpwuid,
getpwuid_r, getuid, initgroups, lacl, lacl32, lchown, lseek, lstat,
mknod, mmap, setegid, seteuid, setgid, setgroups, setregid, setreuid,
setuid, stat, _stat_r, truncate.
[For most of these, the corresponding 64-bit entry points are obtained
by exporting aliases. For example, acl is an alias for acl32, and
truncate is an alias for truncate64.]
Remove the following structs and all code using them (which is 32-bit
only): __stat32, __group16, __flock32, __aclent16_t.
Remove the typedefs of __blkcnt32_t __dev16_t, __ino32_t, which are
used only in code that has been removed.
Put the typedefs of __uid16_t and __gid16_t in one header, instead of
one header if __INSIDE_CYGWIN__ is defined and a different header
otherwise.
