Hmm, I was trying to avoid that but I'm not getting to change newlib
for the necessary fpos_t changes.  And, honestly, I hate digging in
newlib. 

But it's not *that* simple:

- sec_acl.cc is still using __aclent16_t instead of __aclent32_t.

- Create a new define, say __CYGWIN_USE_32BIT_IDS__

- Set this define in some Cygwin header (cygwin/types.h?) or
  in gcc's specs file.

- Change Cygwin's Makefile so that new applications are linked
  against the new functions (same way as for regcomp/posix_regcomp
  et al)

And don't forget that all applications still use 16 bit ids as long
as they aren't rebuild!

Would that imply a chance to correct a mistake in the API?  Once I
introduced a function lacl() which is completely useless and has
never been defined in Solaris nor in POSIX.  May I just trash it then?
